types.c (double): Add AIX and Darwin to the right TYPEDEF.

2003-09-18  Andreas Tobler  <a.tobler@schweiz.ch>
	    David Edelsohn  <edelsohn@gnu.org>

	* src/types.c (double): Add AIX and Darwin to the right TYPEDEF.
	* src/powerpc/aix_closure.S: Remove the pointer to the outgoing
	parameter stack.
	* src/powerpc/darwin_closure.S: Likewise.
	* src/powerpc/ffi_darwin.c (ffi_prep_args): Handle structures
	according to the Darwin/AIX ABI.
	(ffi_prep_cif_machdep): Likewise.
	(ffi_closure_helper_DARWIN): Likewise.
	Remove the outgoing parameter stack logic. Simplify the evaluation
	of the different CASE types.
	(ffi_prep_clousure): Avoid the casts on lvalues. Change the branch
	statement in the trampoline code.
