* alpha-tdep.c, mips-tdep.c (init_extra_frame_info):

	Do not set saved registers from heuristics for a sigtramp frame.

	* dwarfread.c (enum_type):  Determine signedness of enum type
	from enumerators.

	* mips-tdep.c:  Include gdb_string.h, gcc -Wall lint.

	* rs6000-nat.c (xcoff_relocate_core):  Fix typo.

	* valops.c (value_repeat):  Fix length of memory transfer to
	match recent allocate_repeat_value change.
