Minimal graphics gcc lib for MacOS-X

Hi,
A member of my family studies C in his classroom under Windows, and they
use a Windows IDE.
On his MacOS-X Tiger machine, he uses gcc + Emacs, but lacks the
capability of opening a simple graphics window, and drawing lines.
Is there a *small* graphics lib he can include to get his project done
without diving in the arcane of XCode and Mac programming ?
A turtle graphics library should be the ideal so far.
Thanks for him (and probably many other students)...

A few simple Carbon calls will do fine. You don't need any extra library,
just use -framework Carbon on the command line (if you are using the
Terminal). NewCWindow, SetPort, MoveTo, LineTo... Something like this:

---
#include <Carbon/Carbon.h>

Rect bounds;
WindowPtr wind;

main()
{
SetRect(&bounds, 100, 100, 356, 356);
wind =
NewCWindow(NULL,&bounds,"\pTest",1,plainDBox,(WindowPtr)-1,0,
0);
SetPortWindowPort(wind);
while (!Button())
{
LineTo(Random() & 255, Random() & 255);
QDFlushPortBuffer(GetWindowPort(wind), NULL);
}
}
---

It can't be much simpler. Of course, I'd like to suggest OpenGl for the
future.
