 Doh! Than explains a lot. I mean, of course I know that I'm using BSD make, ;-), it just hadn't yet occurred to me that all the wonderful examples I was reading were GNU make specific. My first clue _should_ have been, when reading the man page, that I actually notice the different conditionals! At least I can be embarrassed about this in front of an understanding group. :-)

Yeah, I hadn't yet felt the need to install it, but I can. It is the most straight-forward solution. Though, my program doesn't _have_ to compile on Linux, it's just nice that it can.

  Hmm, OK. I'm just getting started today and haven't yet touched this. I'll play around with this, and see what sort of trouble I can get myself into...

Thanks again Greg,
