On older libc, _POSIX_C_SOURCE didn't satisfy to use posix_fadvise()
and AC_CHECK_FUNCS doesn't check a header file if the function is
declared there properly. so use AC_LINK_IFELSE instead.
X_OK checking was added back in 8ae1e3d5dc
which was removed due to the same reason in
238489030a.
apparently the test case in Bug#18934 still works without it.
so I'm removing it again to get this working on Windows.
Use install-data-hook instead of install-data-local.
This allows on the real installation to create a symlink with
the broken ln command though, still not work with the pseudo
installation by using DESTDIR say.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 8: reading configurations from ~/.fonts.conf.d is deprecated.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
Be polite and do not issue the warning if deprecated config includes
(e.g. ~/.fonts.conf.d and/or ~/.fonts.conf) do not exist.
Windows does not update mtime of directory on FAT filesystem when
file is added to it or removed from it. Fontconfig uses mtime of
directory to check cache file aging and hence fails to detect
newly added or recently removed files.
This changeset detects FAT filesystem (currently implemented for
Linux) and adds generating checksum of directory entries instead
of using mtime which guarantees proper cache rebuild.
For non-FAT filesystems this patch adds single syscall per directory
which is negligeable overhead.

FcStat() logic is quite complicated in presence of various semi-broken operating
systems and filesystems, split it out in order to make it a bit easier.

link(2) might be failed on the filesystem that doesn't support
the hard link. e.g. FcAtomicLock() always fails on FAT filesystem
when link(2) is available.
So that may be a good idea to fallback if link(2) is failed.
Warn if the multiple values is set to <test>, including the case of
in <alias> because the behavior isn't intuitive since so many users
is asking for a help to get things working for their expectation.
Use multiple <match>s or <alias>es for OR operator and
multiple <test>s for AND operator.
