Not really.
You can't pass a char ** to a function that takes a char const **. If
you could, that could create a const violation if you took a char const
*, put it in one of the array elements, then returned to the caller who
would then be able to treat it as a char * and modify it.
You can pass a char ** to a function that takes a char const * const *,
but that's something different.
But I don't think any of this is relevant to the problem the original
poster is reporting, because cpp_main is declared in cpp_main.cpp. In
his case, the signature has to match exactly, not just be compatible.
