Subject: * ns32k-tdep.c (ns32k_call_dummy_words,
 sizeof_ns32k_call_dummy_words, ns32k_fix_call_dummy): New. *
 config/ns32k/tm-umax.h (CALL_DUMMY_WORDS): Define as ns32k_call_dummy_words.
 (SIZEOF_CALL_DUMMY_WORDS): Define as sizeof_ns32k_call_dummy_words.
 (CALL_DUMMY, CALL_DUMMY_LENGTH, CALL_DUMMY_ADDR, CALL_DUMMY_NARGS): Remove.
 (FIX_CALL_DUMMY): Define as ns32k_fix_call_dummy.
