Hello,

This patch introduces a new file i386-windows-nat.c to hold the few
parts of win32-nat that are actually dependent on the host CPU.
So far, I only detected one item, which is the "mappings" array.

2009-01-10  Joel Brobecker  <brobecker@adacore.com>

        * win32-nat.h: New file.
        * win32-nat.c (mappings): Initialize to NULL.
        (win32_set_context_register_offsets): New function.
        * i386-windows-nat.c: New file.
        (mappings): Moved here from win32-nat.c.
        (_initialize_i386_windows_nat): New function.
        * config/i386/mingw.mh (NATDEPFILES): Add i386-windows-nat.o.
        * config/i386/cygwin.mh (NATDEPFILES): Likewise.

Tested on x86-windows.
OK to apply?

Thank you,
