Of course.  As far as DJGPP is concerned, accessing the registers it
outside the scope of GDB (it's part of the library functions which
support the debug API).  All go32-nat.c does is to pass an array with
debug register definitions to the function which runs the debuggee.

I did mean the code which manages the debug registers image maintained
by platform-specific code in GDB.  That part ought to be quite generic
on all x86 targets which use debug registers for watchpoints, modulo
Peter's comment about leaving a possibility to override that for
specific architectures.
