Well, it's been a year, and here i am. Foreseeable future :)
Anyway, here's the patch.
It checks for the cache path starting with '/' and then prepends the
installation prefix (which is already figured out elsewhere in fccfg.c) to it.
This way each fontconfig installation has its own cache, plus there's a
user-specific cache.
This way fc-cache -v outputs:
F:/e43/mingw/var/cache/fontconfig: cleaning cache directory
C:/Users/LRN/.cache/fontconfig: not cleaning non-existent cache directory
C:/Users/LRN/.fontconfig: not cleaning non-existent cache directory
instead of:
C:/Users/LRN/AppData/Local/fontconfig/cache: cleaning cache directory
C:/Users/LRN/.cache/fontconfig: not cleaning non-existent cache directory
C:/Users/LRN/.fontconfig: not cleaning non-existent cache directory
(where F:/e43/mingw is the installation prefix).
FC needs to be configured with
--with-cache-dir='${localstatedir}/cache/${PACKAGE}', because otherwise
LOCAL_APPDATA_FONTCONFIG_CACHE will become the default.
