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.

Mingw is the only known platform that lacks O_NONBLOCK (possibly
via the alternate spelling O_NDELAY). But mingw also lacks any
files where open() needs to enforce non-blocking behavior, and
lacks openat(), so it is relatively simple to provide a non-zero
flag. A future patches will make use of O_NONBLOCK for pipe2.

For years gnulib has been assuming the existence of the headers
<ctime.h>, <errno.h>, <fcntl.h>, <locale.h>, <signal.h>,
<stdio.h>, <stdlib.h>, <string.h>, and <time.h>. Omit checks for
them, since they don't appear to be needed.

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.

Implement F_DUPFD_CLOEXEC. The unit test still fails on systems
with other fcntl bugs (such as cygwin 1.5 mishandling F_DUPFD,
or mingw lacking fcntl altogether). Passes on Linux, both with
and without kernel support, and on cygwin 1.7.

99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
-e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job. For more details, see
<http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/16175>.
