Does anyone know why this program works "as-is" i.e. with no extra
pre-compiler #include lines:

/*---------------------------*/

int main()
{
  getch();
}

/*---------------------------*/

If getch() is declared in conio.h (I think it's in grx20.h as part of the
GRX library, too), then how on earth can gcc under rhide compile the
program, and run it, and return the code of the keypress, without some
header file or other?
