+     [Bodo Moeller]

   *) Rename 'des_encrypt' to 'des_encrypt1'.  This avoids the clashes
      with des_encrypt() defined on some operating systems, like Solaris
      and UnixWare.

+  *) Enhance bctest to search for a working bc along $PATH and print
+     it when found.
+     [Tim Rice <tim@multitalents.net> via Richard Levitte]

   *) Fix memory leaks in err.c: free err_data string if necessary;
      don't write to the wrong index in ERR_set_error_data.
