Update.
1998-06-30 11:47 Ulrich Drepper <drepper@cygnus.com> * include/aio.h: New file. * posix/Makefile (distribute): Add bits/pthreadtypes.h. (tests): Build and run annexc program. * posix/annexc.c: New file. * posix/bits/posix1_lim.h: Add several more _POSIX_* limits. * rt/aio.h: Remove __need_timespec_t. We can include the whole time.h. * rt/aio_misc.c: Include limits.h. * rt/aio_notify.c: Include errno.h. * sysdeps/unix/sysv/linux/alpha/bits/types.h: Include pthreadtypes.h. Define size_t. * sysdeps/unix/sysv/linux/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/bits/errno.h: Define ENOTSUP though the kernel doesn't do this. * sysdeps/unix/sysv/linux/bits/fcntl.h: Define O_LARGEFILE only if __USE_LARGEFILE64 is defined. * sysdeps/unix/sysv/linux/bits/pthreadtypes.h: New file. Empty. * sysdeps/unix/sysv/linux/bits/sched.h: Define __sched_param struct if requested. * sysdeps/unix/sysv/linux/bits/siginifo.h: Protect non-standard names. * stdlib/isomac.c: Avoid include_next warning.
