Modified Files:
        src/gnu/dist/gdb6/gdb: shnbsd-tdep.c

Log Message:
shnbsd_software_single_step: There's no need to write back next_pc and
it actually messes things up if single step was interrupted with a
signal - we end up skipping the instruction we wanted to step.

There are still some corner cases, but at least it works enough to do
useful debugging in presence of signals.  Discovered while debugging
ntpdate where this problem was triggered by SIGALRM.
