Note that I'm working on a unified watchpoint implementation for all
ia32 targets, based on the code written for the DJGPP port (see
go32-nat.c).  This implementation will allow to watch large areas (up
to 16 bytes) and debug register sharing via reference counts (required
for watching overlapping areas) on all ia32 platforms.

I am trying to make this happen for v5.1, so perhaps changes like this
one should be witheld and not committed, at least until we decide that
I'm not living up to my promises.
