Ah, I've found the functions, but I'm not sure which is which...

Here's my guesses, can anyone confirm:

__negdi2            negate                -
__lshldi3           shift left            >>
__lshrdi3           shift right           <<
__ashldi3           ???
__ashrdi3           ???
__ffsdi2            ???
__muldi3            multipy               *
__udiv_w_sdiv       ???
__udivmoddi4        ???
__divdi3            divide                /
__moddi3            mod                   %
__umoddi3           unsigned mod          %
__udivdi3           unsigned divide       /
__cmpdi2            compare               >,>=,<,<=,==,!=
__ucmpdi2           unsigned compare      >,>=,<,<=,==,!=

What happenened to addition and subtraction??

Eli - thanks for pointing djlsr112.zip out to me!

BTW, I seem to be missing "longlong.h".  Anyone got it?  Also, __muldi3 
calls __umulsidi3, which I don't have either.

I've ported negate and compare and tested against a calculator program.  
It works!  The PowerPC is a little endian, but that doesn't seem to be 
causing a problem...

Thanks

Adam
