I don't recall how one gets warnings when compiling this generated code,
but if it is generally possible then I think this:
Marek> + if (indirect)
Marek> + fprintf (stream, "extern void JvRunMainName ();\n");
Marek> + else
Marek> + fprintf (stream, "extern void JvRunMain ();\n");
... will fail with -Wstrict-prototypes, since in C those should
read "(void)" rather than "()".
If it's not possible then no big deal.
