 compile the unpatched port with gcc6 or gcc7?

 Withe `GCC7`:

 I produced a pre-processed output file (-dD -E). It showed clearly that
 `l` has no type. There is another loop with `x` which is initialised
 inside the big-endian code as `int x;`. To me it's clearly overseen that
 `l` needs a type the same way as `x` gets it. Outside the PPC world this
 error simply does not happen.
