* xcoffread.c (read_xcoff_symtab): Fix obsolete comment about 

mst_solib_trampoline.

	* f-valprint.c (f_val_print): Change cast of valaddr from
	CORE_ADDR * to char **, since that is how it is used.

	* dbxread.c (read_dbx_dynamic_symtab): Save copy of symbol names
	using obsavestring, and pass that to prim_record_minimal_symbol.
	Having the objfile point to bfd_asymbol_name directly doesn't work
	if we save and restore a mapped symbol file.
