I'd be willing to make sure it works on freeBSD/Alpha if someone provided
access to a box.
Though i have a penchant for crashing them when porting GDB (it got to the
point where i have a cheap laptop i use specifically as a glorified
movable serial debugger).

Yeah, I really couldn't see a 1.x box lying around either, especially
since most boxen were at the very least, upgraded, when people were
worried about y2k.

This reminds me.
I tried to email you a few months ago, but obrien@freebsd.org didn't work
(5 day timeout bounce, on freebsd's side).
Unless you've changed it when i wasn't looking, you are producing broken
DWARF2 info with GCC.
You have a if (debug_type==DWARF_DEBUG || DBX_DEBUG) type deal in the
config file, and change the register map as a result. However, you also
need to do the same for DWARF2_DEBUG, or else you have the wrong registers
in the info, making it worthless.
It'd be real nice if you fixed this, i hate applying the same 2 line patch
i have over and over, every time i update :).

I track 5-CURRENT, so I can make sure the stuff works on that.
