Description Tim Evans 2006-03-23 14:25:57 UTC 
On win32, unlike Posix, the 'rename' function does not overwrite existing files.
 FcAtomicReplaceOrig expects the Posix behaviour and will always fail under
win32.  This results in fontconfig being unable to replace existing
.fonts.cache-1 files.

The quick solution is to unlink the original file before the rename, but I'm not
sure if this is the correct solution as a failure could leave the original file
deleted and the new file not moved in to replace it.  There may not be better
solution.

I've committed unlink-before-rename on Win32 to HEAD and branch.
