Hi,

This patch should 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.

See for instance http://bugzilla.gnome.org/show_bug.cgi?id=154968 and http://www.codeproject.com/datetime/dstbugs.asp

+ * 2) stat() does some very strange crap related to backward + * compatibility with the local time timestamps on FAT volumes and + * daylight saving time. This causes problems after the switches + * to/from daylight saving time. See + * http://bugzilla.gnome.org/show_bug.cgi?id=154968 , especially + * comment #30, and http://www.codeproject.com/datetime/dstbugs.asp . + * We don't need any of that crap, FAT and Win9x are dead.
