Ok, never mind, forget about WINDRES (and the other tools like RANLIB), that's not required, I just noticed that I simply forgot to specify "--cross-prefix=i686-w64-mingw32-" when running configure. With that option, i686-w64-mingw32-windres is properly used, and the pkg-config problem also goes away since i686-w64-mingw32-pkg-config is used instead. But still, I think at least the PKG_CONFIG_LIBDIR part could be useful, since the same problem e.g. also occurs when trying do a 32-bit build on a 64-bit host, i.e. when running configure with "--extra-cflags=-m32". Or is there also another configure switch that can help to get PKG_CONFIG_LIBDIR right here? Thomas
