Short code fragment in C to test for the presence of Color QuickDraw:

SysEnvRec gEnv;

SysEnvirons (1, &gEnv);
if (gEnv.hasColorQD)
    /* it's present */;
else
    /* it's not present */;

SysEnvirons will tell you other cool things, too, like whether or not
the machine you're on has an FPU (more important to check now than
ever before; my new IIsi won't have one for a while yet...).  Refer to
Inside Macintosh, Volume V, page {something really small, like 4}.

Disclaimer:  I haven't actually *compiled* this, mind you...
