 Version 1.3.18 (In progress)
 ============================
+02/11/2003: beazley
+            Fixed more very subtle preprocessor corner cases related to recursive
+            macro expansion.  For example:
+
+                   #define cat(x,y) x ## y
+
+                   cat(cat(1,2),3)    // Produces: cat(1,2)3
+                   
+                   #define xcat(x,y) cat(x,y)
+
+                   xcat(xcat(1,2),3)  // Produces 123
+
+            See K&R, 2nd Ed. p. 231.
