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. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14943 87f5fb63-7c3d-0410-a384-fd976d0f7a62
