No, the version of GDB we have right now is fine with DWARF2 debug
information. It's easy to test; just build something with
'-gdwarf-2'. We used DWARF2 debug info on i386 for quite a while
before we decided to switch to stabs to avoid the (IMO very minor)
debug-info generation bug. We're using DWARF2 debug information
already on alpha, arm, mips, powerpc, and sparc{64}.

(that said, I expect to get gdb 6.4 in the tree this weekend).
