After some careful adjustments, I see just configure and config.h.in changed. New patch with updated Changelog attached. Be sure to copy config/os/mingw32 over to config/os/mingw32-w64 before continuing. >> I guess its due to libtool versions, any ideas how to fix this? > > Nope, sorry, on Linux, provided the versions are correct - please double > check that, I'm traveling - regen works like a charm.
