I agree this should be fixed.

My suggestion is to copy *.S to *.s (if you look at the .s files
you'll see they are just #include <> anyway), update Makefile.am, and
make sure to pass `-x assembler-with-cpp' to the gcc invocation (we
know only gcc will be used to build libffi) somehow.  (You might think
we could just use *.S but I think that is unreliable.  I've found in
practice that sometimes the case of a file can seemingly randomly be
changed on NT at least.)

I would do this but as it turns out I don't immediately have a
convenient way to test this.  Maybe eventually I'll build a cross
toolchain to try it.  I'd rather someone who builds on the right sort
of machine regularly do it though.
