testing the upcoming libffi release

Hi team,

the libffi project is preparing a release. The current pre-release is
2.99.6, so if you have a chance to give it try on a platform not already
listed at http://sourceware.org/libffi/ , please do, and report the
results back to the libffi mailing list.

It'd be nice to know if we can depend on libffi in Kaffe in particular
on non-mainstream platforms, as it's used and ported by many other
projects, including gcc/gcj & IcedTea, and our own sysdepCallMethod code 
hasn't seen much maintenance.

cheers,
