Work around for bitmap-only TrueType fonts that are missing the glyf table.
Bitmap-only TrueType fonts without a glyf table will not load a glyph when
FT_LOAD_NO_SCALE is set. Work around this by identifying TrueType fonts that have no
glyphs and select a single strike to measure the glyph map with.

Not_contain should use strstr, not strcmp on strings. (bug 13632)
For Version 2.5.0, (same for previous version 2.4.2), in source file fccfg.c,
on line 700,
Original:
ret = FcStrCmpIgnoreCase (left.u.s, right.u.s) == 0;
Should change to:
ret = FcStrStrIgnoreCase (left.u.s, right.u.s) == 0;
I think this is just a mistake when copy-n-paste similar codes in the same
function. Apparently, return for "Not_contain" should be just the inverse of
"Contain", not the same as "Equal".

Workaround for stat() brokenness in Microsoft's C library (bug 8526)
Fix a couple of longstanding problems with fontconfig on Windows that
manifest themselves especially in GIMP. The root cause to the problems is in
Microsoft's incredibly stupid stat() implementation. Basically, stat()
returns wrong timestamp fields for files on NTFS filesystems on machines
that use automatic DST switching.
See for instance http://bugzilla.gnome.org/show_bug.cgi?id=154968 and
http://www.codeproject.com/datetime/dstbugs.asp
As fccache.c now looks at more fields in the stat struct I fill in them all.
I noticed that fstat() is used only on a fd just after opening it, so on
Win32 I just call my stat() replacement before opening instead...
Implementing a good replacement for fstat() would be harder because the code
in fccache.c wants to compare inode numbers. There are no (readily
accessible) inode numbers on Win32, so I fake it with the hash of the full
file name, in the case as it is on disk. And fstat() doesn't know the full
file name, so it would be rather hard to come up with a inode number to
identify the file.
The patch also adds similar handling for the cache directory as for the fonts
directory: If a cachedir element in fonts.conf contains the magic string
"WINDOWSTEMPDIR_FONTCONFIG_CACHE" it is replaced at runtime with a path under
the machine's (or user's) temp folder as returned by GetTempPath(). I don't
want to hardcode any pathnames in a fonts.conf intended to be distributed to
end-users, most of which who wouldn't know how to edit it anyway. And
requiring an installer to edit it gets complicated.

Export FcConfig{G,S}etRescanInverval from .so, mark as deprecated.
These two names are typos of the correct names. Instead of simply changing
them, the correct thing to do is leave them in the library, add the correct
functions and mark them as deprecated so any source packages will be updated.
This requires bumping the minor version of the library (for adding APIs)
instead of bumping the major version of the library (for removing APIs).

The cache was inserted into the hash table before the timestamps in the

Of course the above is nonsense, “mono” is no valid integer indeed.
But I think nevertheless fontconfig should not crash in that case.
The problem was caused by partially truncated expression trees caused by
parse errors -- typechecking these walked the tree without verifying the
integrity of the structure. Of course, the whole tree will be discarded
shortly after being loaded as it contained an error.
