very much! This includes the following:
- Added SSIZE_MAX to <limits.h>.
- Added <sys/uio.h>, readv() and writev().
- Cut back the soft link resolution code in lstat().
- In <fcntl.h> O_NDELAY is now an alias for O_NONBLOCK.
- Added <complex.h>, carg(), cargf(), cargl(), cimag(), cimagf(),
cimagl(), conj(), conjf(), conjl(), creal(), crealf() and creall().
Note that the C99 support for the complex floating point data
types is limited to GCC 3.x for now.
- Added va_copy() to <stdarg.h>.
- Added _Exit() to <stdlib.h>.
- Added <stdbool.h>.
- Added vfscanf() to <stdio.h>.
