Same for 64-bit sparc-sun-solaris2.*.  The following snippet fixes the
cls_unit_va.c failure for me:

diff --git a/libffi/testsuite/libffi.call/cls_uint_va.c
b/libffi/testsuite/libffi.call/cls_uint_va.c

  }

 typedef T (*cls_ret_T)(T, ...);

I've included the complete patch in i386-pc-solaris2.* bootstraps, too,
and saw no regressions, so I suggest you post the complete patch to
gcc-patches, and Cc: Anthony Green.

Thanks.
