Thanks for the list. And Darwin apparently supports DWARF 2. I'm not suprised Cygwin is a sticky one, though, now that you mention it. It seems to me that, for now, it wouldn't be a great idea to convince GCC to generate a fancy version of stabs, then, until somebody appears who's particularly motivated to deal with the issues that arise. So I agree with your planned course of action. David Carlton carlton@math.stanford.edu
