Bug in GNU Prolog 1.3.0: `gplc' ignores the `--c-compiler' option

Please do not be scared by the long `gplc' command line
after the signature.
Just notice that

1) we pass the option `--c-compiler /usr/local/bin/c++' to `gplc';
2) despite that, in the linking phase, `gplc' uses `gcc' to
    perform the job.

If anyone has a patch for this, we would appreciate very
much hearing about it.
All the best,

     Roberto
