Dear Manoj,

OK, I can check the header files.

I don't have the NVIDIA packages installed.  Still, I have tried again
your program on Fedora 8 and nothing bad happens:

$ cat glversion.cpp
#include <ppl.hh>

extern "C" {
#include "GL/gl.h"
#include "GL/glut.h"
#include <stdio.h>
}

int main(int argc, char *argv[])
{
	glutInit(&argc, argv);
	glutCreateWindow("");
	printf("GL Version = %s\n", (char*)glGetString(GL_VERSION));
	return 0;
}
