Without trying to argue with you, I want to ask if you've used the full
warning options that gcc has to offer.  Before doing this comparison,
make sure to check the -Wall and -O switches in the compiler options. 
If you _really_ want gcc to generate warnings, add -W, -ansi, and/or
-pedantic.  :-)

It depends largely on the speed of the system, from what I understand. 
However, have you considered using the <conio.h> functions for this kind
of busy wait output?  They are much more suited for the task than stdio
functions.
