Nice. I tried to make a configure check for libffi so that it sets
LIBFFI_LIBS and LIBFFI_CFLAGS correctly which is a bit of a puzzle since
the debian libffi package installs things just in /usr/include, but with
the new proposed fedora libffi package [*] you have to use pkgconfig
(the debian package doesn't support pkgconfig atm). Attached is a patch
to do that. But now I need to figure out how to pass these flags down to
the openjdk build infrastructure. Anyone know how to do that cleanly?

Thanks,

Mark
