+Description: Switch to system iswspace() function
+ This patch replaces calls to _XmDataFieldIsWSpace() in lib/Xm/DataF.c
+ and _XmTextFieldIsWSpace() in lib/Xm/TextF.c with calls to the system
+ iswspace() function.
+ .
+ It fixes an array bounds error in lib/Xm/DataF.c where
+ _XmDataFieldIsWSpace() is called with num_entries = 3.
