[Coco] Which version of C?

[K. Pruitt]

There seems to be a couple of different versions of C floating around out 
there.  On a coco 3 with a 6809 running NitrOS9 level 2, which version of C 
should I be running?

I remember not really caring for the first C that Tandy had for OS9.  And 
that was my first exposure to C so it kind of soured me on C for a long 
time. I used Turbo C from Borland for a bit. That was pretty fun. And I 
meddled with GCC a bit and it wasn't too disastrous. So I am thinking maybe 
I'll give C on the Coco another shot.

Thanks.
