--- Comment #24 from Eric Pouech eric.pouech@gmail.com ---
it'll:
- keep user default, if any,
- search first for .pc in 32libs
- fallback to 64bit dirs if .pc not found in 32bit dirs, hence working
around Fedora's settings (I don't see a generic for this one, so we need to be prepared for more errors from compilations on Fedora),
- and potentially work around comment #22 (even if I didn't look from where
this could come from)
of course, if won't work if user set 64bit dirs in PKG_CONFIG_PATH
