The following patch fixes gdb/901. I am submitting it on behalf of
Pascal Obry, who found the fix. No new regression on Windows XP.

2002-12-26  J. Brobecker  <brobecker@gnat.com>

        From Pascal Obry  <obry@act-europe.fr>
        * win32-nat.c (SetPrivilege): New routine.
        (Child_Attach): call SetPrivilege to correctly set child
        privileges to be able to debug applications running as services.

Ok to commit?

Thanks,
