Depending on compiler (gcc, g++, clang) and standard options (c99, c11),
string.h may or may not include strings.h, leading to possibly missing
or conflicting declarations of strcasestr.
Include both so that both detection and compilation phases use the same
(possibly optimised) implementations.

When compat canonicalize_file_name was introduced, it was limited to
C code only because it was used by C code only during that time.
>From 5ec6fd4d, (lib/open: check for split configuration when creating
database., 2021-02-16), lib/open.cc, which is C++, relies on the
existent of canonicalize_file_name.
However, we can't blindly enable canonicalize_file_name for C++ code,
because different implementation has different additional signature for
C++ and users can arbitrarily add -DHAVE_CANONICALIZE_FILE_NAME=0 to
{C,CXX}FLAGS.
Let's move our implementation into a util library.

Use `makefile-gmake-mode' instead of `makefile-mode' because the
former also highlights ifdef et al. while the latter does not.
"./Makefile.global" and one "Makefile.local" failed to specify any
major mode at all but doing so is necessary because Emacs does not
automatically figure out that these are Makefiles (of any flavor).
A leading / in paths in a .gitignore file matches the beginning of the
path, meaning that for patterns without slashes, git will match files
only in the current directory as opposed to in any subdirectory.
Prefix relevant paths with / in .gitignore files, to prevent
accidentally ignoring files in subdirectories and possibly slightly
improve the performance of "git status".
The feature test code should test the build environment, and none of
the compat code should interfere with that. Don't include compat.h
from the feature test source. There should be no functional changes
here, but this is just the right thing to do.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
Some systems (e.g. FreeBSD) might not have installed the appropriate
pkg-config file as they should. We can workaround the issue by creating
the .pc file they should have distributed.

the POSIX 2008 behaviour of realpath is not available everywhere so we
provide a simple wrapper function. We use (and provide) the gnu
extension canonicalize_file_name to make it cleaner to test for the
feature we need; otherwise we have to rely on realpath segfaulting if
the second argument is null.
Support for dirent.d_type is OS-specific. Previously, we used
_DIRENT_HAVE_D_TYPE to detect support for this, but this is apparently
a glic-ism (FreeBSD, for example, supports d_type, but does not define
this). Since there's no cross-platform way to detect support for
dirent.d_type, detect it using a test compile at configure time.
The timegm(3) function is a non-standard extension to libc which is
available in GNU libc and on some BSDs. Although SunOS had this
function in its libc, Solaris (unfortunately) removed it. This patch
implements a very simple version of timegm() which is good enough for
parse-time-string.c.

Solaris does not ship a version of the strsep() function. This change
adds a check to "configure" to see whether notmuch needs to provide its
own implementation, and if so, it uses the new version in
"compat/strsep.c" (which was copied from Mutt, and apparently before
that from glibc).

Add checks to "configure" to see whether _POSIX_PTHREAD_SEMANTICS needs
to be defined to get the right number of arguments in the prototypes for
asctime_r(). Solaris' default implementation conforms to POSIX.1c
Draft 6, rather than the final POSIX.1c spec. The standards-compliant
version can be used by defining _POSIX_PTHREAD_SEMANTICS.
This change also adds the file "compat/check_asctime.c", which
configure uses to perform its check, and modifies compat/compat.h to
define _POSIX_PTHREAD_SEMANTICS if configure detected it was needed.

This attribute is understood by gcc since version 2.5. clang provides
support for testing for function attributes using __has_attribute. For
other compilers this macro evaluates to the empty string.

__has_attribute is defined by clang and tests whether a given function
attribute is supported by clang.

This ignores the results of the two writes in sigint handlers even
harder than before.
While my libc lacks the declarations that trigger these warnings, this
can be tested by adding the following to notmuch.h:
__attribute__((warn_unused_result))
ssize_t write(int fd, const void *buf, size_t count);

Such as:
mkdir build
cd build
../configure
make
This is implemented by having the configure script set a srcdir
variable in Makefile.config, and then sprinkling $(srcdir) into
various make rules. We also use vpath directives to convince GNU make
to find the source files from the original source directory.
While all systems that I have access to support strcasestr, it is
in fact not part of POSIX. So here's a fallback reimplementation
based on POSIX functions.

It makes sense to me to have the little tests for functionality right
next to the comptability implementations of that same functionality.
But also, this means I can now tab-complete ./configure from the three
initial characters (rather than the seven required previously).
We add a magic line to the beginning of each Makefile.local file to
help the editor know that it should use makefile mode for editing the
file, (even though the filename isn't exactly "Makefile").
Edited-by: Carl Worth <cworth@cworth.org>: Expand treatment from
emacs/Makefile.local to each instance of Makefile.local.
We were previously maintaining two lists of the child Makefile
fragments---one for the includes and another for the dependencies. So,
of course, they drifted and the dependency list wasn't up to date.
We fix this by adding a single subdirs variable, and then using GNU
Makefile substitution to generate both the include and the dependency
lists.
Some side effect of this change caused the '=' assignment of the dir
variable to not work anymore. I'm not sure why that is, but using ':='
makes sense here and fixes the problem.
Some compilers complain that result might be used uninitialized in
this function. I believe such compilers simply aren't looking hard
enough, but it's easy enough to silence them.
