 * ChangeLog:
 *
 * V 1.10   David G. Holm               Added __MINGW32__ support
 * V 1.8    David G. Holm               Added '&& ! defined(_Windows)'
 *                                      check to all __BORLANDC__ checks.
 * V 1.6    David G. Holm               Added Win32 Beep(), thanks to
 *                                      Chen Kedem.
 * V 1.4    David G. Holm               Upper limit for frequency for OS/2
 *                                      DosBeep() is 32767. The CA-Clipper
 *                                      Tone() function does not have an
 *                                      upper limit on the duration, so I
 *                                      had to add an inner loop to deal
 *                                      with very long durations. There are
 *                                      actually 18.2 Clipper (PC) timer
 *                                      ticks per second.
 * V 1.2    David G. Holm               Added OS/2 GCC/EMX support.
 * V 1.1    David G. Holm               Split machine dependent code into
 *                                      hb_tone() function for internal use
 *                                      by other Harbour C functions.
 * V 1.0    Chen Kedem                  Initial version (only OS/2 support).
