 Thanks for your explanation! I wasn't aware of this important difference.

 > While I'll grant it's possible that the error message is using the
 varargs notation to mean "the arg list is undefined", note that OpenVRML
 is entirely C++; and there is no concept of a declared function with an
 undefined arg list in C++.

 I propose that the configure script should use the C++ compiler instead of
 the C compiler to test for the callback function type, since ISO C
 obviously does not like {{{GLvoid (*)(...)}}}. With the unpatched version
 of your configure script and using the C++ compiler, I finally get the
 correct error on 10.5.5:
 {{{
 error: invalid conversion from ‘GLvoid (*)(...)’ to ‘GLvoid (*)()’
 error:   initializing argument 3 of ‘void gluTessCallback(GLUtesselator*,
 GLenum, GLvoid (*)())’
 }}}
