Looks like your glut version is a little different from what we're
accustomed to compiling against. Looking at the glut spec, those
functions do indeed take char * rather than const char *. Please file a
bug about this.

There's no easy fix for this that doesn't involve getting into the code.
It's actually easy to fix, but you'll have to know a bit about C++ and
constness in order to patch this.

This won't be a problem in future versions of OpenVRML, as we don't use
those constant names anymore. In the meantime, I suggest you simply
delete (or comment out) the offending section of acconfig.h to get
things working.
