Hi Edward,

    Good to know - I think I've only built 32-bit versions with 3.4.3,  
so I haven't run into this particular bug there. I usually do the  
optimized and 64-bit builds with gcc 4.2 or 4.3.

Yes, Sun nm (/usr/bin/nm) produces different output to GNU nm (and the  
XPG4 version is different again, yes), and always has as far as I know  
- this isn't a bug in nm per se. In any case LLVM 2.4 and 2.5 built  
correctly with /usr/bin/nm, so this seems like a regression to me. As  
I said, the best fix is probably to adjust the sed expression so that  
it can handle the output from /usr/bin/nm -p -u (or any other nm we  
know about).

Cheers,
Nathan
