1999-08-18 Ulrich Drepper <drepper@cygnus.com> * Rules: When generating stdio_lim.h also rewrite IOV_MAX definition. * stdio-common/stdio_lim.h.in: Add IOV_MAX template. * include/bits/xopen_lim.h: Don't define IOV_MAX here, get it from stdio_lim.h. Define LONG_BIT and WORD_BIT. * include/features.h: Define __USE_XOPEN2K if _XOPEN_SOURCE == 600. * libio/stdio.h: Don't declare cuserid and getopt for X/Open issue 6. * misc/search.h: Don't define NULL. * posix/sys/types.h: Define blksize_t if it hasn't happened. Only define key_t and blkcnt_t if it hasn't happened before. Define blksize_t if not happened before. * io/sys/stat.h: Don't define pid_t. Define blkcnt_t and blksize_t. * sysdeps/generic/bits/types.h: Define __blksize_t. * sysdeps/unix/sysv/linux/alpha/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/types.h: Likewise. * sysdeps/unix/sysv/sysv4/solaris2/bits/types.h: Likewise. * sysdeps/mach/hurd/bits/stat.h (struct stat): Use __blksize_t for st_blksize member. (struct stat64): Likewise. * sysdeps/unix/bsd/bits/stat.h: Likewise. * sysdeps/unix/bsd/osf/alpha/bits/stat.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/stat.h: Likewise. * sysdeps/unix/sysv/linux/bits/stat.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/stat.h: Likewise. * sysdeps/unix/sysv/sysv4/i386/bist/stat.h: Likewise. * sysdeps/unix/sysv/sysv4/solaris2/bits/stat.h: Likewise. * stdlib/getsubopt.c: Correct type of second argument. * stdlib/stdlib.h: Likewise. * stdlib/monetary.h: Don't include sys/types.h. Define only size_t and ssize_t. * sysdeps/generic/putenv.c: Correct type of parameter. * stdlib/stdlib.h: Likewise. * sysdeps/generic/msgsnd.c: Correct type of second parameter. * sysdeps/unix/sysv/linux/msgsnd.c: Likewise. * sysvips/sys/msg.h: Likewise. * sysdeps/generic/semop.c: Correct type of third parameter. * sysdeps/unix/sysv/linux/semop.c: Likewise. * sysvipc/sys/sem.h: Likewise. Don't include sys/types.h, define size_t. * sysdeps/generic/shmget.c: Correct type of second parameter. * sysdeps/unix/sysv/linux/shmget.c: Likewise. * sysvips/sys/shm.h: Likewise. Don't include unistd.h and sys/types.h. Declare __getpagesize here. * sysdeps/generic/bits/ipc.h: Include bits/types.h instead of sys/types.h. * sysdeps/gnu/bits/ipc.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/ipc.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/ipc.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/ipc.h: Likewise. * sysvipc/sys/ipc.h: Define uid_t, gid_t, mode_t, and key_t if not already done. * sysdeps/unix/bsd/usleep.c: Correct type of parameter. * debug/versions: Export __cyg_profile_func_enter and __cyg_profile_func_exit. * math/bits/mathcalls.h: Pretty print.
