Here is a patch so that unistd.h declares all of gnulib's replacements that
belong there.
getcwd.h and getlogin_r.h are gone. Replaced with <unistd.h>.
2007-02-18 Bruno Haible <address@hidden>
* lib/readlink.c: Include <unistd.h>.
* m4/readlink.m4 (gl_FUNC_READLINK): Require gl_UNISTD_H_DEFAULTS. Set
HAVE_READLINK.
* modules/readlink (Depends-on): Add unistd.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
(Include): Add <unistd.h>.
* lib/getlogin_r.h: Remove file.
* lib/getlogin_r.c: Include <unistd.h> instead of getlogin_r.h.
* m4/getlogin_r.m4 (gl_GETLOGIN_R_SUBSTITUTE): Remove macro.
(gl_GETLOGIN_R): Inline it here. Require gl_UNISTD_H_DEFAULTS. Set
HAVE_DECL_GETLOGIN_R.
* modules/getlogin_r (Files): Remove lib/getlogin_r.h.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
(Include): Use <unistd.h> instead of getlogin_r.h.
* lib/getcwd.h: Remove file.
* lib/getcwd.c: Include <unistd.h> instead of getcwd.h.
* lib/xgetcwd.c: Likewise.
* m4/getcwd.m4 (gl_FUNC_GETCWD): Require gl_UNISTD_H_DEFAULTS. Set
REPLACE_GETCWD. Don't define __GETCWD_PREFIX.
* modules/getcwd (Files): Remove lib/getcwd.h.
(Depends-on): Add unistd.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
(Include): Use <unistd.h> instad of getcwd.h.
* lib/ftruncate.c: Include <unistd.h> first.
* m4/ftruncate.m4 (gl_FUNC_FTRUNCATE): Require gl_UNISTD_H_DEFAULTS.
Set HAVE_FTRUNCATE.
* modules/ftruncate (Depends-on): Add unistd.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
* lib/fchdir.c: Include <unistd.h> first.
* lib/dirent_.h: Test REPLACE_FCHDIR, not FCHDIR_REPLACEMENT.
* m4/fchdir.m4 (gl_FUNC_FCHDIR): Require gl_UNISTD_H_DEFAULTS instead
of gl_HEADER_UNISTD_DEFAULTS. Set REPLACE_FCHDIR. Don't set UNISTD_H.
* modules/fchdir (configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
(Makefile.am): Substitute also REPLACE_FCHDIR into dirent.h.
* lib/dup2.c: Include <unistd.h> first.
* m4/dup2.m4 (gl_FUNC_DUP2): Require gl_UNISTD_H_DEFAULTS. Set
HAVE_DUP2.
* modules/dup2 (Depends-on): Add unistd.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
* lib/chown.c: Include <unistd.h> first. Undefine chown later.
* m4/chown.m4 (gl_FUNC_CHOWN): Require gl_UNISTD_H_DEFAULTS. Set
REPLACE_CHOWN. Don't define chown as a macro here.
* modules/chown (Depends-on): Add unistd.
(configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR.
* lib/unistd_.h: Test HAVE_UNISTD_H determined at configure time.
Add definition for GL_LINK_WARNING.
(chown, dup2): New declarations.
(fchdir): Test REPLACE_FCHDIR, not FCHDIR_REPLACEMENT. Provide optional
link warning.
(ftruncate): New declaration.
(getcwd): New declaration, taken from old getcwd.h.
(getlogin_r): New declaration, taken from old getlogin_r.h.
(readlink): New declaration.
* m4/unistd_h.m4 (gl_UNISTD_H): Renamed from gl_HEADER_UNISTD. Don't
set UNISTD_H. Inline gl_PREREQ_UNISTD. Set HAVE_UNISTD_H.
(gl_PREREQ_UNISTD): Remove macro.
(gl_UNISTD_MODULE_INDICATOR): New macro.
(gl_UNISTD_H_DEFAULTS): Renamed from gl_HEADER_UNISTD_DEFAULTS. Set
many new variables. Don't set UNISTD_H.
* modules/unistd (Description): Change.
(Depends-on): Add link-warning.
(configure.ac): Update.
(Makefile.am): Create unistd.h always. Substitute many new variables
into it.
