  * - works only on x86 architectures

  * $Log$
+ * Revision 1.25  2001/06/17 22:21:47  acki2
+ * - if DGA fails to report some valid modes, vo_dga now exits gracefully
+ *   instead of crashing ... (100000x100000 bug ...)
+ *
  * Revision 1.24  2001/06/17 20:59:39  acki2
  * - doublebuffering now can be switched on and off with the -(no)double switch.
  *   Default in libvo is disabled.
