At least default for -g can be redefined. I haven't looked  for 
corresponding definitions about -ggdb.

Today built entire rhtvision-1.13 with gcc-3.0.3 and used -ggdb3.
This time I haven't noticed serious problems tracing TVision demo program 
with RHGDB (from rhide-1.4.9.1).

However I used binutils 13 November CVS snapshot but not 
binutils-2.11.2.   So with not very old CVS version of binutils and GDB-5.1 
DWARF2 debug info could be useable.
