Whoa.  Those fortnights are sneaky.  But I have finally committed to
master, before a second fortnight could slip past!  I have yet to
rebase Gtk onto this new "FFIs support", but I added a little test
library, and it works on i386, x86_64 and portable C (on i386).
(Thanks be to Taylor for the `make check' encouragement!)

Add your-FFI to FFIS in src/configure.ac and it will appear in
src/Makefile (and src/Makefile.in) and get built and installed
automatically, on any of the aforementioned machinery, assuming
src/your-FFI/Makefile-fragment has working build and install targets
(almost, but NOT similar to src/ffi/Makefile-fragment).  There are
several files that may want patching, unfortunately, like
src/Setup.sh, src/TAGS, src/etc/create-makefiles.sh, and
src/etc/optiondb.scm.  When Gtk is rebased, I can provide a working
example.
