[RFA] Avoid compiler warnings in mips-tdep.c

[Eli Zaretskii <eliz@is.elta.co.il>]

Please consider the following patches to mips-tdep.c, to avoid compiler 
warnings and fix one typo in a comment.


2001-05-17  Eli Zaretskii  <eliz@is.elta.co.il>

	* mips-tdep.c (show_mipsfpu_command): Remove unused variable msg.
	(mips_set_processor_type_command): Remove unused variable j.
	(mips_breakpoint_from_pc): Declare breakpoint instruction
	sequences as unsigned char, to avoid compiler warnings.
