Phasing out Dwarf 1?

For gdb 6.1, I get some noise, but the backtrace looks okay:

  (top-gdb) backtrace

This is on a native i686-pc-linux-gnu, red hat enterprise linux 3,
gdb compiled with gcc 3.2.3-24-rh.  "make CFLAGS=-gdwarf"

I get similar three messages "During symbol reading ..." with gdb 6.0
operating on gdb 6.0, and also gdb 5.3 operating on gdb 5.3.

I already posted this link from February 2003:

  http://sources.redhat.com/ml/gdb-patches/2003-02/msg00293.html

I will do it again with gdb 6.1 but it will take some time.

It looks like gdb is working, with some glitches, and the test suite
has been busted for a while.
