OK, I checked this in with the minor modifications in the code discussed and with this
modified log entry.

PS:
   I must confess that I was unable to recheck my patch as there seems to be a 
configure problem for cygwin lately.


2002-02-04  Pierre Muller  <muller@ics.u-strasbg.fr>
         Add support for hardware watchpoints for win32 native.
         * win32-nat.c (CONTEXT_DEBUG_DR macro): Add use of 
         CONTEXT_DEBUG_REGISTERS.
         (dr variable): New variable. Static array containing a local copy 
         of debug registers.
         (debug_registers_changed): New variable.  Reflects when debug registers
         are changed and need to be written to inferior.
         (debug_registers_used): New variable. Reflects when any debug register 
         was set, used when new threads are created.
         (cygwin_set_dr, cygwin_set_dr7, cygwin_get_dr6): New functions used by
         i386-nat code.
         (thread_rec): Set dr array if id is the thread of current_event .
         (child_continue, child_resume): Change the debug registers for all
         threads if debug_registers_changed.
         (child_add_thread): Change the debug registers if debug_registers_used.
         * config/i386/cygwin.mh: Add use of i386-nat.o file.
         Link nm.h to new nm-cygwin.h file.
         + config/i386/nm-cygwin.h: New file. Contains the macros used for use
         of hardware registers.
