That's the version I have, and gcc complains about passing from an 
incompatible pointer type if when inbuf is passed from a const char **.

The __restrict stuff is a mystery to me, but it doesn't look as though 
it can be defined so as to change the declaration to a const char **. 
So until the header file gets updated, I believe we need the cast.
