This is the same bug I reported several months ago; I don't think
anyone has replied.  I don't have GCC 3.0.3 installed yet, but I
tried with GCC 3.0.2, and I see the same problem with all versions of
GDB, including the latest and greatest 5.1.1.

Andris, did you try Martin's example with GCC 3.0.3 and GDB 5.1.1,
and didn't see the problem with COFF debug info?

Try "objdump --debugging c.exe", and you will see a lot og bogus line
numbers there.  So the problem is not in GDB, but either in GCC or in
Binutils.

Right, same here with GDB 5.1 and 5.1.1.

This does work for me, so I think Andris is right: your Binutils need
to be updated (I have the latest upload of 2.11.2 from SimTel).
