I believe I've seen reports before about our version of gdb and 64-bit
systems.
It may be a better idea to try and use the latest gdb from the GNU
website. As you may have seen from recent posts, it works out of the box
with cegcc, so I think we should remove the old gdb from the cegcc
source tree...
