* sysdeps/unix/dirstream.h: Rewritten. * sysdeps/unix/readdir.c: Rewritten. * sysdeps/unix/telldir.c: Rewritten. * sysdeps/unix/closedir.c: Use <...> instead of "..." for dirstream.h. Remove __ from DIR struct member names. * sysdeps/unix/dirfd.c: Likewise. * sysdeps/unix/seekdir.c: Likewise. * sysdeps/unix/rewinddir.c: Likewise. * sysdeps/unix/opendir.c: Likewise. Don't allocate extra space after DIR structure. * sysdeps/stub/direct.h: File removed. * sysdeps/unix/bsd/bsd4.4/direct.h: File removed. * sysdeps/unix/bsd/direct.h: File removed. * sysdeps/unix/common/direct.h: File removed. * sysdeps/unix/sysv/irix4/direct.h: File removed. * sysdeps/unix/sysv/isc3/direct.h: File removed. * sysdeps/unix/sysv/sco3.2.4/direct.h: File removed. * sysdeps/unix/sysv/sysv4/solaris2/direct.h: File removed. * sysdeps/unix/common/direntry.h: New file. * sysdeps/unix/bsd/direntry.h: New file. * sysdeps/unix/bsd/bsd4.4/direntry.h: New file. * sysdeps/unix/sysv/direntry.h: New file. * sysdeps/stub/direntry.h: New file. * dirent/dirent.h (struct dirent): Type removed. Include <direntry.h> to define it. (_D_EXACT_NAMLEN, _D_ALLOC_NAMLEN): New macros. * dirent/Makefile (headers): Add direntry.h. (distribute): Remove direct.h. * sysdeps/posix/getcwd.c: Use new macros instead of d_namlen. * dirent/scandir.c: Likewise. * io/fts.c (fts_build): Likewise. * io/ftw.c (ftw_dir): Likewise. * sysdeps/posix/ttyname.c: Likewise. * sysdeps/unix/sysv/sysv4/solaris2/syscalls.list: New file. * sysdeps/mach/hurd/profil.c (MAX_PC_SAMPLES): New macro. (collector_timeout): New static variable. (update_waiter): Actually call __task_enable_pc_sampling. Set collector_timeout based on the `tick' count returned. (profile_waiter): Use MAX_PC_SAMPLES. Set nsamples before RPC. Use collector_timeout in __mach_msg call. * gmon/Makefile (noprof): New variable containing mcount. Append profil unless it is in $(unix-syscalls). (mcount.po): Use $(noprof) for list of targets in this rule. * libc-symbols.h: Define _LIBC before #include <config.h>. Sun Feb 25 12:29:23 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> * config.h.in [_LIBC] (HAVE_STRERROR): Define it. Protect 2nd page of #undef's for generator programs with #ifndef _LIBC. * time/zic.c, time/zdump.c, time/private.h: Updated from ADO's latest. Fri Feb 9 12:40:19 1996 Brendan Kehoe <brendan@lisa.cygnus.com> * libio/cleanup.c (_IO_cleanup_registration_needed) [!_G_HAVE_ATEXIT]: Init to NULL. * libio/filedoalloc.c (_IO_cleanup_registration_needed): Remove decl. Thu Feb 8 08:12:50 1996 Brendan Kehoe <brendan@cygnus.com> * libio/filedoalloc.c (_IO_cleanup_registration_needed): Revert previous change, since cleanup.c only defines it if _G_HAVE_ATEXIT. Wed Feb 7 15:10:17 1996 Brendan Kehoe <brendan@lisa.cygnus.com> * libio/filedoalloc.c (_IO_cleanup_registration_needed): Declare as extern. Sat Feb 24 11:34:13 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> * sysdeps/i386/memcmp.S: Fix argument %esp offsets. * time/sys/time.h (timeradd, timersub): New macros; BSD has these.
