No, I meant configuring the 'cross-debugging' gdb that I use on the x86
host. I think standard 5.0 will support the mipsel-linux-elf target also
(but something later is better). As for gdbserver... yes, you'll be out
of luck... that's why I have to hand build (cross compile) it (pending
getting the config stuff sorted out).

It's actually a tar bundle that we include on one of our CDs. I think
it's a gdb snapshot dating from around August or September last year.
I'll see if I can dig out some more info and let you know. Or you could
try the latest snapshots, I haven't tried them, but they're probably OK.

Sure, just give me a bit of time to get something together... it's a bit
rough round the edges at the moment :)
