Warning patches installed

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

I installed the following "obvious" warning fixes after successfully
bootstrapping the patch on mips-sgi-irix6.2 and sparc-sun-solaris2.7.

		--Kaveh



2000-10-16  Kaveh R. Ghazi  <ghazi@caip.rutgers.edu>

	* mips.h (REG_CLASS_FROM_LETTER): Cast array arg to unsigned char.

	* sparc.c (load_pic_register): Delete unused varaible.

	* libgcc2.c (__addvsi3): Delete unused variable.

	* libgcc2.h (__absvsi2, __absvdi2, __addvsi3, __addvdi3,
	__subvsi3, __subvdi3, __mulvsi3, __mulvdi3, __negvsi2,
	__negvdi2): Prototype.

	* ssa.c (apply_delayed_renames): Avoid undefined operation.

	* toplev.c (display_target_options): Make static to match
	prototype.  Delete empty declaration.
