- Pass -Wno-error=pedantic to work around ISO C violations
- Build with X11 unconditionally (also rely on pkgconfig for
detection, --enable-x11 does not work)
- Build against evemu
This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
