No, that version is not usable because the underlying API's (WGL and GLX) have since updated and using that ancient version of GLUT will not allow you to use OpenGL 3+ at all. There's also a bunch of other features introduced by WGL and GLX API changes. The original GLUT was written for an OpenGL book (IIRC, the red book) so that the code examples wouldn't occupy so much space on paper. It wasn't probably intended to be used for real applications at all.
