Version 3.21.74 - Maintenance release

   initialize active_modem
       * initialize active_modem pointer to point to
         an instance of NULLMODEM, before any other threads
         or UI are started.
       * eliminates active_modem pointing to a NULL pointer
         and being accessed by a thread external from the
         thread which initializes the active modem.  This
         segmentation fault seems associated with an OS
         which manages threads over multiple cpu cores.

   XML parser
       * Pre-process the xml text to remove all embedded comments
       * LOG_ERROR all occurrences of mangled xml tags in the file
         - <TAG> ... no </TAG>
         - Tag not a member of the parent tag set
         - Unknown tag
         - Mismatched tags, <TAG>...</ATAG>; probably a typing error
           or not using an xml editor to prepare the file.

   64 bit compile warnings
       * corrected code to eliminate 64 bit compiler warnings

   Automake bug
       * Versions 1.12, 1.13, 1.14xxx of Automake introduces
         a bug that precludes the use of $(srcdir) within
         the "TESTS = " line of a Makefile.am file.
