I am guessing there is some static or extern declaration that clashes with what is in NVIDIA's driver. I have emailed linux-bugs@nvidia.com asking if I can email some their header files to you for you to see if you can spot some clashing variables.
Dear Manoj,
OK, I can check the header files.
BTW, I have the following nvidia packages installed on my Fedora 8 system:
kmod-nvidia-169.12-7.lvn8 xorg-x11-drv-nvidia-devel-169.12-1.lvn8 kmod-nvidia-2.6.24.5-85.fc8-169.12-7.lvn8 kmod-nvidia-2.6.24.4-64.fc8-169.12-6.lvn8 xorg-x11-drv-nvidia-libs-169.12-1.lvn8 xorg-x11-drv-nvidia-169.12-1.lvn8
I don't have the NVIDIA packages installed. Still, I have tried again your program on Fedora 8 and nothing bad happens:

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; }
