Well I'm the reporter, so I guess that don't count as an additional
+1, but just searching "fontconfig cache directory" on the web, I can
find several bug reports and discussion about it. On launchpad for
Ubuntu for instance, I found 2 bug reports:
https://bugs.launchpad.net/inkscape/+bug/1021815
https://bugs.launchpad.net/inkscape/+bug/1196373

They are both for inkscape and are about the same path issue. I've
seen other reports for VLC or mplayer, related to fontconfig cache
taking time to generate, regularly, but they did not say what was the
actual issue in the reports when closing it. So I can't say for sure
that was the same path issue.

In any case, the main problem is that Windows builds of various
software will likely bundle fontconfig in their installer. So that
makes as many fontconfig built by people who did hope that the default
would be ok and won't try to change the configure settings. There is
hardly one fontconfig installation and a knowledgeable maintainer for
this specific package. So flawless default config prevents bad
surprises in the various projects (like GIMP, Inkscape, etc.) who make
win32 builds.

And in any case, it is always better to have reasonable defaults for a
given platform, isn't it? :-)

Thanks.
