[src/ChangeLog]
Work around some portability problems with symlinks.
* fileio.c (Frename_file, Fmake_symbolic_link, Ffile_symlink_p):
Simplify the code by assuming that the readlink and symlink calls
exist, even if they always fail on this host.
(Ffile_readable_p): Likewise, for fifos.
* config.in: Regenerate.
* configure: Rebuild.
* configure.in (NS_OBJC_OBJ): New subst.
lib-src
* make-docfile.c: Unconditionally include stdlib.h.
(generate_globals): New global.
(xrealloc): New function.
(main): Handle '-g'. Call start_globals, write_globals.
(scan_file): Conditionally call put_filename.
(start_globals): New function.
(struct global): New.
(num_globals, globals): New globals.
(add_global, compare_globals, write_globals): New functions.
(scan_c_file): Update for "-g".
(scan_lisp_file): Fail if "-g".
(enum global_type): New.
src
* Makefile.in (NS_OBJC_OBJ): New variable.
(base_obj): Rename from 'obj'.
(obj): New variable.

2011-01-19T22:11:33Z!jan.h.d@swipnet.se.

variable.

This makes src/config.in a bit smaller, by removing identifiers
like GNULIB_TEST_MKTIME that Emacs does not need.

* m4/multiarch.m4, m4/stddef_h.m4, m4/time_h.m4, m4/unistd_h.m4:

src/config.in, such as AA_APPLE_UNIVERSAL_BUILD and HAVE_STDDEF_H.
