 * SF [Bug #126733] XmFRAME_TITLE_CHILD label doesn't scale:
     I'm not much of an Motif expert, but I noticed a difference in behaviour
     of a XmFRAME_TITLE_CHILD label widget between IBM's AIX ( with
     Motif ) and Linux ( with Lesstif ofcourse...)
     If the label is changed using Xt(Va)SetValues the string doesn't display
     completely if the new labelstring is longer than the initial labelstring.
     On AIX it displays correctly ( or maybe I should say 'like expected' :-) )
 *
 * Compile with 'cc framelabel.c -lXm -lXt -lX11'
 *
