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.
Using a simple shell script that processes the public headers, two header
files are constructed that map public symbols to hidden internal aliases
avoiding the assocated PLT entry for referring to a public symbol.
A few mistakes in the FcPrivate/FcPublic annotations were also discovered
through this process
On Windows with gcc (a.k.a. mingw) build as a DLL.
We don't want to hardcode the fonts.conf file location in the DLL, so we
look up the DLL location at run-time in a DllMain() function. The
fonts.conf location is deduced from that.
The colon can't be used as path separator on Windows, semicolon is used
instead. File path components can be separated with either slash or
backslash. Absolute paths can also begin with a drive letter.
Add internal function FcStrLastSlash that strrchr's the last slash, or
backslash on Windows.
There is no link() on Windows. For atomicity checks, mkdir a lock directory
instead.
In addition to HOME, also look for USERPROFILE.
Recognize the special font directory token WINDOWSFONTDIR, to use the
system's font directory.
Remove the fontconfig-def.cpp that was obsolete. Add fontconfig.def(.in),
without internal functions.
Add a fontconfig-zip(.in) script, used to build a binary distribution.
