-/****************************************************************************
-
-getopt.h - Read command line options
-
-AUTHOR: Gregory Pietsch
-CREATED Thu Jan 09 22:37:00 1997
-
-DESCRIPTION:
-
-The getopt() function parses the command line arguments.  Its arguments argc
-and argv are the argument count and array as passed to the main() function
-on program invocation.  The argument optstring is a list of available option
-characters.  If such a character is followed by a colon (`:'), the option
-takes an argument, which is placed in optarg.  If such a character is
-followed by two colons, the option takes an optional argument, which is
-placed in optarg.  If the option does not take an argument, optarg is NULL.
-
-The external variable optind is the index of the next array element of argv
-to be processed; it communicates from one call to the next which element to
-process.
-
-The getopt_long() function works like getopt() except that it also accepts
-long options started by two dashes `--'.  If these take values, it is either
-in the form
-
---arg=value
-
- or
-
---arg value
-
-It takes the additional arguments longopts which is a pointer to the first
-element of an array of type GETOPT_LONG_OPTION_T, defined below.  The last
-element of the array has to be filled with NULL for the name field.
-
-The longind pointer points to the index of the current long option relative
-to longopts if it is non-NULL.
-
-The getopt() function returns the option character if the option was found
-successfully, `:' if there was a missing parameter for one of the options,
-`?' for an unknown option character, and EOF for the end of the option list.
-
-The getopt_long() function's return value is described below.
-
-The function getopt_long_only() is identical to getopt_long(), except that a
-plus sign `+' can introduce long options as well as `--'.
-
-Describe how to deal with options that follow non-option ARGV-elements.
-
-If the caller did not specify anything, the default is REQUIRE_ORDER if the
-environment variable POSIXLY_CORRECT is defined, PERMUTE otherwise.
-
-REQUIRE_ORDER means don't recognize them as options; stop option processing
-when the first non-option is seen.  This is what Unix does.  This mode of
-operation is selected by either setting the environment variable
-POSIXLY_CORRECT, or using `+' as the first character of the optstring
-parameter.
-
-PERMUTE is the default.  We permute the contents of ARGV as we scan, so that
-eventually all the non-options are at the end.  This allows options to be
-given in any order, even with programs that were not written to expect this.
-
-RETURN_IN_ORDER is an option available to programs that were written to
-expect options and other ARGV-elements in any order and that care about the
-ordering of the two.  We describe each non-option ARGV-element as if it were
-the argument of an option with character code 1.  Using `-' as the first
-character of the optstring parameter selects this mode of operation.
-
-The special argument `--' forces an end of option-scanning regardless of the
-value of `ordering'.  In the case of RETURN_IN_ORDER, only `--' can cause
-getopt() and friends to return EOF with optind != argc.

-/* This file can define macros to choose variations of the IEEE float
-   format:
-
-   _FLT_LARGEST_EXPONENT_IS_NORMAL
-
-	Defined if the float format uses the largest exponent for finite
-	numbers rather than NaN and infinity representations.  Such a
-	format cannot represent NaNs or infinities at all, but it's FLT_MAX
-	is twice the IEEE value.
-
-   _FLT_NO_DENORMALS
-
-	Defined if the float format does not support IEEE denormals.  Every
-	float with a zero exponent is taken to be a zero representation.
- 
-   ??? At the moment, there are no equivalent macros above for doubles and
-   the macros are not fully supported by --enable-newlib-hw-fp.
-
-   __IEEE_BIG_ENDIAN
-
-        Defined if the float format is big endian.  This is mutually exclusive
-        with __IEEE_LITTLE_ENDIAN.
-
-   __IEEE_LITTLE_ENDIAN
- 
-        Defined if the float format is little endian.  This is mutually exclusive
-        with __IEEE_BIG_ENDIAN.
-
-   Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a
-   platform or error will occur.
-
-   __IEEE_BYTES_LITTLE_ENDIAN
-
-        This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation 
-	whereby multiple words of an IEEE floating point are in big endian order, but the
-	words themselves are little endian with respect to the bytes.
-
-   _DOUBLE_IS_32BITS 
-
-        This is used on platforms that support double by using the 32-bit IEEE
-        float type.
-
-   _FLOAT_ARG
-
-        This represents what type a float arg is passed as.  It is used when the type is
-        not promoted to double.

-/* This header file provides the reentrancy.  */
-
-/* The reentrant system calls here serve two purposes:
-
-   1) Provide reentrant versions of the system calls the ANSI C library
-      requires.
-   2) Provide these system calls in a namespace clean way.
-
-   It is intended that *all* system calls that the ANSI C library needs
-   be declared here.  It documents them all in one place.  All library access
-   to the system is via some form of these functions.
-
-   The target may provide the needed syscalls by any of the following:
-
-   1) Define the reentrant versions of the syscalls directly.
-      (eg: _open_r, _close_r, etc.).  Please keep the namespace clean.
-      When you do this, set "syscall_dir" to "syscalls" and add
-      -DREENTRANT_SYSCALLS_PROVIDED to newlib_cflags in configure.host.
-
-   2) Define namespace clean versions of the system calls by prefixing
-      them with '_' (eg: _open, _close, etc.).  Technically, there won't be
-      true reentrancy at the syscall level, but the library will be namespace
-      clean.
-      When you do this, set "syscall_dir" to "syscalls" in configure.host.
-
-   3) Define or otherwise provide the regular versions of the syscalls
-      (eg: open, close, etc.).  The library won't be reentrant nor namespace
-      clean, but at least it will work.
-      When you do this, add -DMISSING_SYSCALL_NAMES to newlib_cflags in
-      configure.host.
-
-   4) Define or otherwise provide the regular versions of the syscalls,
-      and do not supply functional interfaces for any of the reentrant
-      calls. With this method, the reentrant syscalls are redefined to
-      directly call the regular system call without the reentrancy argument.
-      When you do this, specify both -DREENTRANT_SYSCALLS_PROVIDED and 
-      -DMISSING_SYSCALL_NAMES via newlib_cflags in configure.host and do
-      not specify "syscall_dir".
-
-   Stubs of the reentrant versions of the syscalls exist in the libc/reent
-   source directory and are provided if REENTRANT_SYSCALLS_PROVIDED isn't 
-   defined.  These stubs call the native system calls: _open, _close, etc. 
-   if MISSING_SYSCALL_NAMES is *not* defined, otherwise they call the
-   non-underscored versions: open, close, etc. when MISSING_SYSCALL_NAMES
-   *is* defined.
-
-   By default, newlib functions call the reentrant syscalls internally,
-   passing a reentrancy structure as an argument.  This reentrancy structure
-   contains data that is thread-specific.  For example, the errno value is
-   kept in the reentrancy structure.  If multiple threads exist, each will
-   keep a separate errno value which is intuitive since the application flow
-   cannot check for failure reliably otherwise.
-
-   The reentrant syscalls are either provided by the platform, by the 
-   libc/reent stubs, or in the case of both MISSING_SYSCALL_NAMES and 
-   REENTRANT_SYSCALLS_PROVIDED being defined, the calls are redefined to
-   simply call the regular syscalls with no reentrancy struct argument.
-
-   A single-threaded application does not need to worry about the reentrancy
-   structure.  It is used internally.  
-
-   A multi-threaded application needs either to manually manage reentrancy 
-   structures or use dynamic reentrancy.
-   
-   Manually managing reentrancy structures entails calling special reentrant
-   versions of newlib functions that have an additional reentrancy argument.
-   For example, _printf_r.  By convention, the first argument is the
-   reentrancy structure.  By default, the normal version of the function
-   uses the default reentrancy structure: _REENT.  The reentrancy structure
-   is passed internally, eventually to the reentrant syscalls themselves.
-   How the structures are stored and accessed in this model is up to the
-   application.
-
-   Dynamic reentrancy is specified by the __DYNAMIC_REENT__ flag.  This
-   flag denotes setting up a macro to replace _REENT with a function call
-   to __getreent().  This function needs to be implemented by the platform
-   and it is meant to return the reentrancy structure for the current
-   thread.  When the regular C functions (e.g. printf) go to call internal
-   routines with the default _REENT structure, they end up calling with 
-   the reentrancy structure for the thread.  Thus, application code does not
-   need to call the _r routines nor worry about reentrancy structures.  */

- * The following definitions are an extension of the behavior originally
- * implemented in <sys/_posix.h>, but with a different level of granularity.
- * POSIX.1 requires that the macros we test be defined before any standard
- * header file is included.
- *
- * Here's a quick run-down of the versions:
- *  defined(_POSIX_SOURCE)		1003.1-1988
- *  _POSIX_C_SOURCE == 1		1003.1-1990
- *  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
- *  _POSIX_C_SOURCE == 199309		1003.1b-1993
- *  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
- *					and the omnibus ISO/IEC 9945-1: 1996
- *  _POSIX_C_SOURCE == 200112		1003.1-2001
- *  _POSIX_C_SOURCE == 200809		1003.1-2008
- *
- * In addition, the X/Open Portability Guide, which is now the Single UNIX
- * Specification, defines a feature-test macro which indicates the version of
- * that specification, and which subsumes _POSIX_C_SOURCE.
- *
- * Our macros begin with two underscores to avoid namespace screwage.

- * This file defines four types of data structures: singly-linked lists,
- * singly-linked tail queues, lists and tail queues.
- *
- * A singly-linked list is headed by a single forward pointer. The elements
- * are singly linked for minimum space and pointer manipulation overhead at
- * the expense of O(n) removal for arbitrary elements. New elements can be
- * added to the list after an existing element or at the head of the list.
- * Elements being removed from the head of the list should use the explicit
- * macro for this purpose for optimum efficiency. A singly-linked list may
- * only be traversed in the forward direction.  Singly-linked lists are ideal
- * for applications with large datasets and few or no removals or for
- * implementing a LIFO queue.
- *
- * A singly-linked tail queue is headed by a pair of pointers, one to the
- * head of the list and the other to the tail of the list. The elements are
- * singly linked for minimum space and pointer manipulation overhead at the
- * expense of O(n) removal for arbitrary elements. New elements can be added
- * to the list after an existing element, at the head of the list, or at the
- * end of the list. Elements being removed from the head of the tail queue
- * should use the explicit macro for this purpose for optimum efficiency.
- * A singly-linked tail queue may only be traversed in the forward direction.
- * Singly-linked tail queues are ideal for applications with large datasets
- * and few or no removals or for implementing a FIFO queue.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may be traversed in either direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
- * after an existing element, at the head of the list, or at the end of
- * the list. A tail queue may be traversed in either direction.
- *
- * For details on the use of these macros, see the queue(3) manual page.
