Read chapter 9.4 of the DJGPP Frequently Asked Questions list
(v2/faq210b.zip or online at http://www.delorie.com/djgpp/v2faq/). 
You're attempting to mix stdio functions with conio functions, which is
never guaranteed to work as you intend.  The fact that it may do so
under certain MS-DOS compilers is accidental rather than intentional. 
:-)

In order to make your screen display appear correctly, you should either
substitute stdio output functions for the equivalent conio versions
(printf->cprintf, etc.), or insert fflush(stdout) after every call to
printf(), etc.
