It may be that the headers don't match the library. Do you have
another set of OpenGL headers installed, e.g. in
/usr/X11R6/include/GL?

OTOH, the test which do_zoom.c uses is wrong. It is basing the
decision on whether to use GLX 1.3 functions on whether or not
GLX_PBUFFER_WIDTH is defined, when it should be testing
GLX_VERSION_1_3.
