  Assume platform function round() is available and works correctly.
  Some platforms don't have round() (it is defined in C99) and on some
  platforms (e.g. some uclibc environments) it may not be provided even
  though the compilation environment is nominally C99.

  Removed in Duktape 2.0.0: if the platform doesn't have round(), simply
  define a replacement for DUK_ROUND().  Currently DUK_ROUND() isn't used
  at all however.
