True, but it doesn't fully support gcc 3.4.x due to the .rdata alignment
issue:

I think we should start by simply enabling its output in gcc 3.4.x via
-gdwarf-2.  It appears that Gerrit included my patches to do this in the
current 3.4.1 experimental release (Thanks, Gerrit.).  Then, we can test
and determine if it should be the default debugging output instead of
stabs.  This decision should be entirely independent of the DWARF 2 vs.
sjlj EH one, which I have no opinion or expertise with.

And BTW, we need a new gdb to handle DWARF 2.
