amiga-clib2/library/include/complex.h
Olaf Barthel 539cc3553d - Added isunordered(), isgreater(), isgreaterequal(), isless(), 
islessequal() and islessgreater() to <math.h> for C99.

- The wchar_t type is now an 'unsigned short' integer (16 bits wide).

- Added PTRDIFF_MIN/PTRDIFF_MAX, WCHAR_MIN/WCHAR_MAX and
  WINT_MIN/WINT_MAX to <stdint.h> for C99.

- Added imaxdiv() and imaxabs() for C99.

- Added strtoimax() and strtoumax() for C99.

- Added nextafter() and nextafterf() for C99.

- Added copysign() and copysignf() for C99.

- Unless I missed something, clib2 should now be functionally complete
  with regard to C99, except for the floating point operations covered.
  These are a major challenge all by themselves, and I wonder both
  whether they are worth the effort and how one could implement them
  correctly.

- fflush() now consistently supports a NULL parameter, causing all
  streams to be flushed for which this behaviour is defined.
