* mips-tdep.c (mips_print_register): Print integers using

Browse Source 
print_scalar_formatted rather than duplicating all the
	CC_HAS_LONG_LONG and so on.
	(mips_push_dummy_frame): Use read_register_gen rather than using
	read_register and then putting it back in target format with
	store_unsigned_integer.  If registers are more than 4 bytes, give
	an error rather than have some registers overwrite other
	registers.
	#if 0 unused include of opcode/mips.h.

#if 0 unused include of opcode/mips.h.
* symfile.h: Don't declare arguments for coff_getfilename.
* defs.h: Revert Kung change regarding FORCE_LONG_LONG.
