You can get the information about the what kind of graphics you are on
from gversion at run time.  There is a man page on it, but a quick summary
might look like this:

#include <gl.h>

main() {
	char version[12];

	noport();
	winopen("");
	gversion(version);
	printf("%s\n",version);
}

the output of this program will look something like this:

GL4D-x.x   on a 4D/70G
GL4DGT-x.x on a GT or GTX
GL4DPI-x.x on a Personal Iris

where x.x is the release of the OS that you are running on.
