The cast is required because C is too stupid to implicitly cast
"nested" non-const objects to const. That is, if you pass a char* to a
function that takes const char*, you get no warning, but if you pass a 
char** to a const char** function then you get warned.

The cast is unfortunate but inevitable, because there's no way to know
whether users will have a const char* const* or a const char** or a
char** or what. So some users will have to put in a cast no matter
what you do.
