The following simple patch seems to make hbreak work for me.  (You may 
need to run configure, as I am not sure the Makefile copies nm-go32.h 
into nm.h.)

I have no idea why was DECR_PC_AFTER_HW_BREAK set to zero; I think 1 is 
the correct value.

Watchpoints still don't work, at least sometimes, but that is the case 
with Robert's binary (and with GDB 4.16) as well.
