Ok, as expected, the 64-bit port fails due to a base compiler which is 
too old. The one failure I mentioned open, you can ignore. This is just 
a warning.

The 32-bit port is much more worse, I didn't know that there are 
gcc-2.95 around. No chance with such an old compiler. Sorry.

I think the last GPLv2 compiler is 4.2.1, this one should be a candidate 
for OpenBSD as well. I have at least on FreeBSD good results on powerpc 
and amd64. The failures in the log of the 64-bit ports are gone with a 
recent compiler, with recent I mean one of the 4.x series.

I bet the 32-bit port will behave equally with a recent compiler.

Well, there is one minor issue which might have to be fixed in the 
libffi package for sparc, 32-bit.

        * src/sparc/ffi.c (ffi_prep_cif_machdep): Add support for
        signed/unsigned int8/16 return values.
        * src/sparc/v8.S (ffi_call_v8): Likewise.
        (ffi_closure_v8): Likewise.

This one has to be merged towards libffi on sourceware. I'll ping AG for 
this.
