I used the following trick on Linux, and I think it should work on any 
posix: call select on stdin i.e. fd_set with one descriptor for reading 
- 0 and timeout of 0. This way you'd get something close to a test for 
keypress.
		
However that will check if there is a data in stream, so it's quite 
possible to hit any number of "press any key" in advance, so some 
flushing of input in the "wait till keypress" function is needed.
