The problem is that sometime between 1.0 and 1.1, NetBSD was changed to
use PT_GETREGS / PT_SETREGS for getting and setting registers.  Our own
gdb was updated, but the changes were not integrated into the FSF 
version.

I am currently doing the work necessary so that gdb 4.16 will compile
out of the box when it is released.
