DJGPP has a 'feature' not occuring in several other compilers, where the
stdout is buffered. Put a \n at the end of the line and it should print when
the statement is executed, not when the buffer is next flushed. You could
also flush the buffer with fflush. It's mentioned in the FAQ, but I can't
remember where.
