As the libc.inf explains, gppconio_init() is automatically called at 
startup by your program if you use conio functions, so it is of 
absolutely no use in standard programs.

However, if your program calls another program which modifies the screen 
registers (or, for instance, calls a DOS shell where a console 
modification is done), when you go back to the main program, you may need 
gppconio_init() to restore the conio functions.
