* valops.c (value_cast): Cehck for cast to array type *before*

	we coerce array to pointer (in case arg2 is already array).

	* valops.c (call_function_by_hand):  Set using_gcc to 2 if using
	gcc2.  Needed for REG_STRUCT_HAS_ADDR to work on sparc.
	Also check REG_STRUCT_HAS_ADDR for union, array and string types.

	* valops.c (call_function_by_hand):  Re-arrange code for pushing
	paramaters on the stack so we can do better STACK_ALIGN.

	* valops.c (call_function_by_hand):  Call error if the number
	of arguments is fewer than parameter types in function type.
