is it easy to do, and is it without any speed loss? then yes, maybe.
otherwise leave it, no one should use 2.95.2 nowdays.

but it makes portability much harder. not all unices like to link objects
from assembler and c compiler, they sometimes uses different symbol
mangling... this is why we changed separate asm files to inline.
i think no one should use so old and buggy compiler...

gabucino refuses to update docs nowdays...
