Reported by Reuben Thomas <rrt@sc3d.org> in
<https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00104.html>.
This is done by defining the Gnulib module indicator variables per
gnulib-tool invocation. So that a generated .h file is no longer
influenced by the set of modules used in other gnulib-tool invocations.
* gnulib-tool (func_compute_include_guard_prefix): Set
module_indicator_prefix.
(func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Use it to
modify $(GNULIB_*) variable references in the Automake snippets.
(func_emit_initmacro_start): Push macro definitions for GL_MACRO_PREFIX
and GL_MODULE_INDICATOR_PREFIX.
(func_emit_initmacro_end): Pop these macro definitions.
* pygnulib/GLConfig.py (GLConfig.getIncludeGuardPrefix): New method.
* pygnulib/GLEmiter.py (GLEmiter.initmacro_start): Push macro
definitions for GL_MACRO_PREFIX and GL_MODULE_INDICATOR_PREFIX.
(GLEmiter.initmacro_end): Pop these macro definitions.
(GLEmiter.lib_Makefile_am, GLEmiter.tests_Makefile_am): Use the module
indicator prefix to modify $(GNULIB_*) variable references in the
Automake snippets.
* m4/gnulib-common.m4 (gl_MODULE_INDICATOR_INIT_VARIABLE,
gl_MODULE_INDICATOR_SET_VARIABLE): Use the value of
GL_MODULE_INDICATOR_PREFIX.
* m4/arpa_inet_h.m4: Use new idiom for header files that contain
references to Gnulib module indicator variables:
- Define the main macro through AC_DEFUN_ONCE.
- Define a macro gl_*_H_REQUIRE_DEFAULTS that initializes the Gnulib
module indicator variables (each prefixed with
GL_MODULE_INDICATOR_PREFIX).
- Invoke this macro in the gl_*_MODULE_INDICATOR macro.

It appears that we may have overengineered lchmod and fchmodat,
in that the code was prepared for some hypothetical platforms but
was so complicated that it was hard to understand. I attempted to
improve the situation by simplifying the code when this
simplification should not hurt on real platforms; we can re-add
complexity later to port to platforms I didn’t know about.
* lib/fchmodat.c (fchmodat):
* lib/lchmod.c (lchmod):
Put the ‘defined __linux__ || defined __ANDROID__’ #ifdef only
around the /proc code that needs it.
* lib/fchmodat.c (fchmodat): Coalese calls to orig_fchmodat.
* lib/lchmod.c (__need_system_sys_stat_h): Omit; no longer needed.
Do not include <config.h> twice.
(orig_lchmod) [HAVE_LCHMOD]: Remove, since we need not wrap
lchmod on any known hosts.
(lchmod): Do not defer to fchmodat, so that the lchmod module
need not depend on the fchmodat module (which is a circular
dependency). Do not use openat, since ‘open’ suffices.
Coalesce calls to lchmod/chmod.
* lib/lchmod.c, lib/sys_stat.in.h (lchmod):
* m4/sys_stat_h.m4 (REPLACE_FSTAT):
* modules/lchmod (Depends-on, configure.ac):
* modules/sys_stat (Depends-on):
Do not worry about replacing lchmod, since that shouldn’t happen.
* m4/lchmod.m4 (gl_FUNC_LCHMOD): Do not check for fchmodat.
Do not worry about whether lchmod works on non-symlinks,
since every known lchmod works on non-symlinks.
* modules/lchmod (Depends-on):
Remove circular dependency on fchmodat.

Fix lchmod, and fchmodat with AT_SYMLINK_NOFOLLOW, so that

Each *.in.h file serves two purposes - provide enough self-contained
content to serve as a replacement for the system header regardless of
the user's compiler, and offer the developer the ability to detect any
gnulib modules that might have been inadvertantly excluded. The
former requires independence from config.h, and routes everything
through a Makefile.am snippet that uses @@ substitution specific to
the modules that were in use, with details learned at configure time.
The latter works by poisoning anything that gnulib did not replace,
but which the developer had natively available, explaining why their
tests passed during development. Poisoning relies on gcc features,
and requires manual triggering by adding -DGNULIB_POSIXCHECK to
CFLAGS; it assumes that <config.h> is properly included. In fact, we
do not want to use @@ substitution for HAVE_DECL_* during poisoning,
because the warning is only relevant for the gnulib modules which were
not included, and thus where the m4 macros to set proper @@ values
have not been run. Furthermore, we only need to poison interfaces
that already have a declaration; if something is not declared, then
the developer wouldn't have been able to link, so their code won't be
using the problematic interface in the first place.

The openat module required lstat, but then repeated the checks
for whether lstat worked. When cross-compiling to mingw, this
led to a wrong answer and tried compiling lstat.c, even though it
was not necessary, with a result of a compiler warning about
undeclared lstat.
* m4/lstat.m4 (gl_FUNC_LSTAT): Avoid duplicate calls to
AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK, and deal with missing
lstat ourselves.
* lib/lstat.c [!HAVE_LSTAT]: Do nothing if <sys/stat.h> override
was adequate.
* m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): Let lstat module handle
the checks for lstat.
(gl_SYS_STAT_H_DEFAULTS): Set default for HAVE_LSTAT.
