[Bug libffi/29181] New: libffi/src/powerpc/ffi_darwin.c not 64-bit clean

["howarth at nitro dot med dot uc dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

When compiled at -m64 on Darwin PPC, we get the warning...

../../../../gcc-4.2-20060915/libffi/src/powerpc/ffi_darwin.c: In function
'ffi_prep_args':
../../../../gcc-4.2-20060915/libffi/src/powerpc/ffi_darwin.c:117: warning: cast
from pointer to integer of different size

for the line...

    *next_arg++ = (unsigned)(char *)ecif->rvalue;

It would appear that we should be doing the same thing as in libffi.c...

+    *next_arg++ = (unsigned long)(char *)ecif->rvalue;

   /* Now for the arguments.  */
   for (;

I will be testing this fix tonight and seeing if it improves the current
level of failures for the libffi testsuite at -m64 on Darwin PPC.
