Andreas,
I just finally (8 months - a new record?) got around to testing gdb6 port
with your patches. (Sorry, forgot about it for a while after other things
took priority) I don't know if you're still even interested in working on
this, but here's what I've found: So far most things seem to be working
quite well, the only problem I've found is 'info threads'/thread switching
doesn't work ('info threads' displays nothing, switching throws an error).
Still, it's far better than the base gdb, since that one wouldn't even run
threaded programs.
