Maybe.  Even after my merge there will be some remaining differences.

*  Libtool differences

*  GPL v3 differences, unless we bump libffi to GPL v3 as well

My first wodge of changes will be only the substantive differences
in the library itself: later I'll get to the testsuite and the rest.
To begin with, I'm just going to update upstream libffi with the gcc
changes, and then see how much difference there is.  I'm guessing not
much.

Questions for Anthony Green:

1.  I don't understand the libffi version numbers.  Can you give
me any explanations?  It seems to be 3.0.8 upstream but 2.1 in gcc,
but this doesn't seem in any way to correspond with reality.

2.  What's with the ChangeLog.libffi and ChangeLog.libgcj files?

Thanks,
Andrew.
