Reverse the change of 1998-04-22. Providing a struct dirent with different members when __USE_FILE_OFFSET64 is defined is asking for trouble. Instead add the necessary LFS magic to the 4.4BSD header. * sysdeps/unix/bsd/bsd4.4/bits/dirent.h: Add LFS definitions. * sysdeps/mach/hurd/bits/dirent.h: Removed. * sysdeps/mach/hurd/readdir64.c: Removed. * sysdeps/mach/hurd/readdir64_r.c: Removed. * sysdeps/generic/bits/mman.h [__USE_MISC] (MAP_ANONYMOUS): Define as alias for MAP_ANON. * stdio/stdio.h (sys_errlist, sys_nerr, _sys_errlist, _sys_nerr): Remove decls. They don't exist at all on the Hurd.

1998-12-06 Mark Kettenis <kettenis@phys.uva.nl>
|
||||
|
||||
Reverse the change of 1998-04-22. Providing a struct dirent with
|
||||
different members when __USE_FILE_OFFSET64 is defined is asking
|
||||
for trouble. Instead add the necessary LFS magic to the 4.4BSD
|
||||
header.
|
||||
* sysdeps/unix/bsd/bsd4.4/bits/dirent.h: Add LFS definitions.
|
||||
* sysdeps/mach/hurd/bits/dirent.h: Removed.
|
||||
* sysdeps/mach/hurd/readdir64.c: Removed.
|
||||
* sysdeps/mach/hurd/readdir64_r.c: Removed.
|
||||
|
||||
1998-12-20 Roland McGrath <roland@baalperazim.frob.com>
|
||||
|
||||
* sysdeps/generic/bits/mman.h [__USE_MISC] (MAP_ANONYMOUS): Define as
|
||||
alias for MAP_ANON.
|
||||
|
||||
* stdio/stdio.h (sys_errlist, sys_nerr, _sys_errlist, _sys_nerr):
|
||||
Remove decls. They don't exist at all on the Hurd.
|
||||
|
||||
* sunrpc/svc_unix.c, sunrpc/clnt_unix.c: Avoid using `struct cmsghdr'
|
||||
and `struct ucred' #ifndef SCM_CREDENTIALS.
