Newer versions of GCC (the Cygnus version, EGCS, and FSF GCC 2.8 if it
ever ships) support Dwarf2 to various targets. Whether it is heavily
used, I dunno, but I suspect it is too new to have been heavily used
at this point.

I've seen people using stabs, Dwarf1, MIPS ECOFF debug information
smuggled into ELF. I imagine you could do COFF debug information if
you really wanted to. With regards to GCC based environments, stabs
is the most prevalent. Several of the ABIs that I'm familar with are
sticking with Dwarf1 with extensions for C++ due to the fact that
Dwarf2 is not a standard (the committee essentially went away before
it became an offical standard).
