Often a simpler way is to use the built-in C Console available in both
Symantec and Metrowerks C/C++. Your first call to printf(), cout, etc..
initializes the MacOS and displays a console window. Every call to a
console function also automatically calls WaitNextEvent() so the programs
do cooperative multitasking by default. 

If the code uses long calculations that don't display results, additional
calls to WaitNextEvent(nullEvent, sleeptime, &myIgnoredEvent, NULL);
placed inside the main loop will allow it to be very well behaved.

Admittedly, addition of these extra calls is not "a simple compile". But
it is trivial compared to the complexity of most programs. Considering how
poorly many UNIX compilers implement ANSI standards (IMHO), going from one
UNIX C compiler to another can be more work. ( I've seldom found "portable
C code" to be really portable -- until it's actually been ported at least
once. :-) )
