dnl This macro figures out what libraries are required on this platform
|
||
|
|
dnl to link sockets programs.

dnl
|
||
|
|
dnl The common cases are not to need any extra libraries, or to need
|
||
|
|
dnl -lsocket and -lnsl. We need to avoid linking with libnsl unless we
|
||
|
|
dnl need it, though, since on some OSes where it isn't necessary it
|
||
|
|
dnl will totally break networking. Unisys also includes gethostbyname()
|
||
|
|
dnl in libsocket but needs libnsl for socket().
