Damien George 17598d49e1 unix: Don't use -Wno-error=cpp or #warning; fix strict alias warning.
For the sake of older versions of gcc (and other compilers), don't use
the #warning CPP directive, nor the -Wno-error=cpp option.

Also, fix a strict alias warning in modffi.c for older compilers, and
add a test for ffi module.

Addresses issue #847.
