In DJGPP, stdio functions are buffered: the strings you write with printf 
(for instance) are written into a buffer, which is output to the screen 
either when the buffer is full, or when a "\n" is seen, or when you call 
fflush(stdout). 

To make your program behave the way you want it to, you may either
- use printf("testing\n"); (note the \n)
- use cprintf instead of printf
- call fflush(stdout) after printf() so that the contents of the printf 
are dumped to the screen.
