Did you use the configure script and provided the host?

configure --host=x86_64-w64-mingw32?

Because that is required to enable the 64bits mode on my end.

I've compiled libffi in 64bits mode without troubles with mingw-w64
compiler, see binary packages mentioned here:

https://groups.google.com/forum/?fromgroups=#!topic/rubyinstaller/Lp-OukkdGQE

The 64bits version was obtained using tdm64 variant of mingw-w64, but
is mingw-w64 at the end. The trick is always configure with the right
host flag.

Let us know if that helps.
