    Many thanks for your help.

    Unfortunately, although your program compiles beautifully, it produces no
    beep at all.  And yes, I knew that the beep should come from the beeper,
    not from the sound boxes (speakers).  ;-)

    I sent your code to a friend in the US who has Borland's C/C++ compiler.
    He compiled it with minor changes, zipped the executable and sent it to me.
    The exe he created *does* produce a 1-second beep on the beeper!  So,
    not only do I have a beeper but it can indeed beep!  Don't know what to
    think anymore -- maybe I found a little bug in GCC?

    Before I raise any eyebrows, I must say that I am not trolling, I'm not willing
    to start a flame war and above all I am not into the familiar this-compiler-is-
    better-than-that-one rubbish.  I'm just reporting things I've found.

    Thanks again and regards,
