I forgot to mention that I made it against 3.4 sources.
The attached patch is against CVS HEAD.

I tested it some more and it doesn't give regressions (and as mentioned
above eclipse 2.1.2 runs with this). But I haven't checked against Mauve
yet. And I found at least one example which breaks with this code. I
made the attached Invoke.java test (using reflection to call an
interface method on an object that implements that interface).
I cannot figure out what I changed that causes this to fail with my
patch. Anyone a clue?

It might be a good idea to add this small test to testsuite/libjava.lang
since it seems a strange corner case that isn't normally tested/used.

Note that is only a port of the original patch to CVS head, I have not
yet implemented any of the suggestions of Tom and Bryce (who was so nice
to take a look and give some comments on IRC). The patch also includes
the fix that was made for 3.4 to get interpret.cc working again
(http://gcc.gnu.org/PR13468 [3.5 Regression] interpret.cc should
register ffi closure stubs).

Cheers,

Mark
