My appologies .. 

I had some time today to acually look around in the config.log .. here is the 
whole bit.. 

the configure test program code is c++ 

test.cc 

-------
#include "test.h"
#include <GL/gl.h>
#include <GL/glu.h>
#define GLH_EXT_SINGLE_FILE
#include <glh/glh_extensions.h>
int main ()
{
  glh_init_extensions ("GL_ARB_multitexture " "GL_NV_vertex_program " 
"GL_NV_fragment_program ");
  ;
  return 0;
}
-------

test.h 

-------
#define PACKAGE "OpenEXR"
#define VERSION "1.0.5"
#ifdef __cplusplus
#include <stdlib.h>
#endif
#define HAVE_DLFCN_H 1
#define STDC_HEADERS 1
#define HAVE_LIMITS_H 1
#define HAVE_UNISTD_H 1
#define HAVE_SYS_TYPES_H 1
#define HAVE_SYS_STAT_H 1
#define HAVE_STDLIB_H 1
#define HAVE_STRING_H 1
#define HAVE_MEMORY_H 1
#define HAVE_STRINGS_H 1
#define HAVE_INTTYPES_H 1
#define HAVE_STDINT_H 1
#define HAVE_UNISTD_H 1
#define HAVE_STRERROR 1
#define HAVE_IOS_BASE 1
#define restrict
-------

So my innitial gcc -o is not valid in this for error reporting.

g++ -o test -g -O2 -lGL test.cc is the compiling commands for the test program 
that fails.

The output is still 

In file included from test.cc:5:
/usr/include/glh/glh_extensions.h: In function `int glh_init_extensions(const
   char*)':
/usr/include/glh/glh_extensions.h:201: `extEnd' undeclared (first use this
   function)

Regardless of adding -UNIX or -lGLX 

Any other help would still be appreciated
