+Changes between versions 0.4b9 and 0.4b10 (released ???????????????)
+====================================================================
+
+1.	Make configure test if the system glob routines support 
+	extended syntax (ALTDIRFUNC). If not, use the internal glob
+	routines instead of system ones.
 
 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
