Most likely fixed by (just need testing):
2003-10-07  Geoffrey Keating  <geoffk@apple.com>

	* function.c (pad_to_arg_alignment): Take STACK_POINTER_OFFSET into
	account	when aligning arguments.
	* calls.c (STACK_POINTER_OFFSET): Move default from here ...
	* defaults.h (STACK_POINTER_OFFSET): ... to here.
	* config/sparc/sparc.h (STACK_BOUNDARY): Add comment about how
	it's wrong when TARGET_ARCH64 && TARGET_STACK_BIAS.
	(SPARC_STACK_BOUNDARY_HACK): Define.
	* config/rs6000/rs6000.c (function_arg): On non-SVR4 systems,
	arrange for vector parameters to varargs functions to be passed
	in both memory and GPRs when appropriate.
	(rs6000_va_arg): Vector arguments passed in memory are 16-byte
	aligned.
