Okay, reading the description, it seems to make a big deal of not being binary compatible with code not compiled with this option. Perhaps the best solution would be to simply prepend all assembler names with underscores? Anyone have any experience with using gAS and GCC together. What is the common practice? I hope I'm not imagining, but I did some work using gcc and external assembler (s files), using the m68k. I don't recall name mangling being an issue.
