No, I doesn't work on Solaris. See below.

Yes, the same is true for dbx on Solaris.

Wine currently works under dbx the problem is that single step
doesn't work, since Wine doesn't use pthreads
it doesn't understand that the application is multithreaded
and does the wrong thing. Breakpoints work fine though,
regardless on which thread that hits the breakpoint.

Unfortunetely Wine with pthreads on Solaris doesn't work. See below.

Don't know, I don't run Wine on Linux very much.

BTW, doesn't pthreads on Linux us the gs register?
It does on Solaris. 

Doesn't that cause any problems? Of course
most applications doesn't use the gs register
but some might.

Well, if you link Wine with pthread on Solaris 2.6,
and run it, the kernel crashes and if you are lucky
the machine reboots by itself.

This problem was reported to Sun by Ulrich IIRC a long time ago.
However it is still true for Solaris 2.6 even with the latest
kernel updates. I haven't tested with Solaris 7 and 8 though.
