The FFIPlugin will need updates in addition to the support code.
There are a fair number of casts between 64-bit machine addresses
and 32-bit sqInt. I've been looking into this recently and will
report back if I make any kind of progress.
I don't have a clue how to write the stack frame setup in
assembler, but Andreas wrote the any-libffi.c that seems like
it should work fine if I can sort out the type casting problems.
If you or someone else knows how to do the assembler bits, that
would be a good thing too.
