Actually it outputs dwarf3 32bit by default. So this is a misunderstanding
here.

Even if gcc is outting for 64bit, GCC defaults to outputting 32bit dwarf[2-5]. 

GCC 11 (r11-5742-g65312dfc647444) adds an option to change to outputting 64bit
dwarf[2-5] though. (note only powerpc-aix defaults to 64bit dwarf output; all
other targets use 32bit dwarf).

I think RedHat 4.4.4 is nowhere close to FSF GCC 4.4.x what debug info
is concerned.  Thus I would suggest to report this bug to RedHat
and/or try to reproduce the issue with a stock FSF GCC.
