     Hi,

     I have the lesstif-current (almost new - from a few days ago). What result 
     should be after this:

     #include <Xm.h>

     main()
     {
      XmString s1, s2; 
      s1 = XmStringCreateLtoR("ala ma pieska", "");
      s2 = XmStringCreateLocalized("ala ma pieska"), 
      printf("%d\n", XmStringCompare(s1, s2));
     }


     In Lesstif this program prints 0, original Motif returns 1.
     I think this is because in Lesstif XmStringCompare() uses
     XmStringByteCompare(). So I wrote my own version XmStringCompare().
     I found this bug while having problems with XmSelectionDialog. Below
     are: test program and patch to XmString.c. Also I changed 
     _XmStringGetNextSegment(). When compound string does not contain direction
     component, or component == XmSTRING_DIRECTION_DEFAULTS (0xff)- it returns
     XmSTRING_DIRECTION_L_TO_R (0x0, not 0xff).

     I hope you understand me, my English sucks :(

     greetings
