Actually, I didn't have the ".a" just -lcrtend.

In possibly related news I just checked out the latest llvm from cvs and 
compiled it. Guess what, there were 6 warnings in the output and 3 of 
them were "gccld: warning: Cannot find library 'crtend'". The last one 
was just before the end:

I haven't tried seeing if anything works (getting past my bed time:), 
but could this have something to do with my using X86-64 (Amd64)? Also, 
I'm using gcc-4.0.2 and glibc appears to be 2.3.5 (symbolic link from 
libc.so.6 is libc-2.3.5.so).

Note: I'm new to linux, in case it wasn't obvious.

Cheers,

Wink
