Objective-CL now includes its own version of libffi, imported from an

The downside? We now depend on autoconf. I don't consider this a
problem, though.

There's a good chance that I've figured out what to do about the
=char/int= mess. As it turns out, it isn't even limited to =chars=, as
-=shorts= are affected, too. According to the code I took from PyObjC,
-specifically the typespec conversion functions in =libffi_support.m=, both
-GNUstep and NeXT/PowerPC treat =chars= and =shorts= as =ints=. The only

I figure the reason I never saw this problem in GNUstep is probably
endianness. The little-endian x86 lets you treat pointers to =ints= as
