[M3devel] cm3 on snow leopard?

[Mika Nystrom]

Thanks, Jay.

I wasn't able to use your Darwin.config (remember, I'm installing
from the release .deb)---there seem to have been too many changes to
these files for me to be able to sort it all out.  However, I figured
out how to do a "quick and dirty" from your email.

This fixed it for me:

if not defined("SYSTEM_ASM")
  SYSTEM_ASM="/usr/libexec/gcc/darwin/i386/as"
end

Now to check on all the other problems.
