Subject: 	* mips-tdep.c, remote-mips.c, values.c, mdebugread.c, 
 config/mips/tm-mips.h: Add/fix bugs for 64-bit mips support. 	* defs.h:
 Cleanup; add prototypess 	* corefile.c: Change FIXME #ifdef 	*
 win32-nat.c: Include windefs instead of windows.h. 	* utils.c: Add
 routines for printing addresses and registers 	based on type size.
