[geoffk at gcc dot gnu dot org]

The gcc.dg/darwin-longlong.c and gcc.dg/darwin-misaligned.c testcases are failing to build on the 3.4 
branch after this patch:

2004-06-08  Richard Henderson  <rth@redhat.com>

       PR middle-end/15228
       * function.c (assign_parms): Always set_mem_align with the computed
       FUNCTION_ARG_BOUNDARY.  Don't clear stack_parm if !STRICT_ALIGNMENT.

with this ICE (this example from darwin-longlong.c):

/Users/regress/tbox/cvs-gcc/gcc/gcc/testsuite/gcc.dg/darwin-longlong.c: In function `msw':
/Users/regress/tbox/cvs-gcc/gcc/gcc/testsuite/gcc.dg/darwin-longlong.c:14: internal compiler error:
