* 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.
