I am on a Linux 1.3.8 system with ELF as native object format, with
gcc 2.7.0 and friends. -g works OK for me, it generates stabs format
info (I think). I think that the executable format and the debug info
format are to some degree independent of each other. Also, I think it
was one of the purposes of ELF to increase that degree of
independence.

So far, just so much babble (I hope some expert can correct me). Now,
however, I have a question of my own. Before this upgrade, I had a.out
Linux version 1.0.9 and 1.2.5, with gcc 2.5.8. It used to be that when
I compiled and linked with -g and I had undefined external references,
the link phase error message contained the _source line_ of the
reference. That meant I could jump right to the problem spot in emacs
the same way as with compile time errors.

In fact I remember using this as an example of the superiority of free
tools over behemoth `IDEs'.

But now after this move to ELF and 2.7.0, this feature seems to be
gone! Why, or am I missing something?
