If FcConfigHome() is NULL, use the temp folder. (I guess this branch
    doesn't crash on a NULL config->cache, but still a good idea to have a

Fix cut&paste error.
Remove CRs from the out file before comparing (needed on Windows).
Add share/doc directory. Add Fc*.3 man pages.
Move the LIBRARY and VERSION lines to the end, not to confuse libtool,
    which expects the EXPORTS line to be the first. Add FcConfigEnableHome.
Check also for DLL_EXPORT as indication of being built as a DLL on Win32.
