Well, actually it would be much easier for me if gcc could handle this :) Keeping 2500 lines of assembly code in sync is not really easy. > The ABI > is different, and to work fully with gcc, assembly code really needs > DWARF2 unwinder data, and that makes no sense at all to Windows. Huh? I thought unwind data is only needed for C++-Exceptions, isn't it? Sebastian
