[plt-scheme] Problems compiling mzscheme 4.2.4.2 on Solaris i386

Eli,

I don't know who maintains the (customized) libffi in mzscheme, but the libff library can't be compiled on Solaris/x86, because the Sun assembler does not support the syntax "xxxx-.", the few occurences that there are should be replaced with "xxxx at rel". (ofcourse with added conditional testing)

I tried compiling mzscheme without libffi, but then you get a limited scheme interpreter, which is not able among other things to run the webserver.

Below you can find the patches I applied to your sources (mz-4.2.4.5) and it compiled.
So nothing to do with an old gcc version (the one I first tried was a gcc 3.x), because you get the same errors with a gcc 4.x
True the libffi problem has been solved in gcc 4.x, but mzscheme uses its own version of libffi (which is still a 3.x version).


Kind regards,
Johan Coppieters.
