In glut_dstr.c there is logic based on GLX_SGIS_multisample that also ought to support the ARB version: GLX_ARB_multisample.

Recent Nvidia drivers don't seem to support the SGIS extension, but _do_ support the ARB extension.

Tested with the following GLUT call on Linux:

glutInitDisplayString("rgb double depth samples~4");

Without the patch glutCreateWindow fails.

Some more observation in support of this patch:

Note that glut_win.c already does support GLX_ARB_multisample.

However, glut_overlay doesn't seem to.

Thanks.  I've applied your patch and updated glut_overlay.c too.
