       * src/x86/win32.S (ffi_prep_args):  Declare extern, not global.
       (_ffi_call_SYSV):  Add missing function type symbol .def and
       add EH markup labels.

       * src/powerpc/ffi.c: Add two new flags to indicate if we have one
       register or two register to use for FFI_SYSV structs.
       (ffi_prep_cif_machdep): Pass the right register flag introduced above.
       (ffi_closure_helper_SYSV): Fix the return type for
