+
+	* out-mips.c (function_arg_partial_nregs): Fix passing two
+	structures, each of which contains two doubles to a function which
+	returns a structure -- the problem was caused when the 1.37.1 code
+	was modified to have two fields for the FUNCTION_ARG routines,

+	the total number of words passed, instead of the old arg_number
