With Fedora, there is a minor configuration issue: like many packages, libffi headers are not installed on a standard path, so relies on pkg-config to supply cflags/libs arguments. I was able to build by simply adding symbolic links in /usr/include. After some investigation, it seems a more general solution can be achieved with the PKG_CHECK_MODULES macro in configure but I don't know whether Fedora is just an unusual case regarding libffi setup.

I've updated configure to use PKG_CHECK_MODULES and it works for me on Debian as before. I've also managed to get it work with mingw once I sorted out pkg-config. Can you check that it now works for you without the symbolic links?
