On my test of #include <windows.h> the object count dropped from

total bytes objs time(ms)

+
+2003-03-06 Doug Schaefer
+	Some minor fixes to get constructors/destructors parsing as well as some minor clean up and robustness.
+
+2003-03-06 John Camelon
+	added quickParse heuristic to Scanner for handling #if conditionals to avoid throwing 
+	ScannerExceptions on undefined preprocessor symbols
+	added minimal enum support to Parser (though not to DOM or CModel)
+
+2003-03-06 Andrew Niefer
+	Implementation of Namespaces & using directives in new parser's symbol table
+
+2003-03-05 Doug Schaefer
