wow .. that's really old and out of date.

I have this :

$ cc -V
cc: Sun C 5.8 Patch 121016-08 2009/04/20

I also have multiple other revs on other architectures also.

The problem is probably with as, the assembler. But I'm guessing.

Well, I have the very latest patches for all compilers.

Yes, this is ABI=32 on a 32-bit system.

Is there a way for force the usage of the more portable "generic" C sources?
