Comment (by wolfgang):

 Some counter-arguments to consider:

  * Mac OS X/x86 is not supported (so unless we fix libffi, we need to keep
 Adjustor.c & ByteCodeFFI around anyway).

  * {{{libffi}}} is maintained as part of gcj, not gcc itself and is
 therefore slightly less universal.

  * {{{libffi}}} is only available as part of the GCC source distribution.
