 ===========================
 
+2011-06-19: wsfulton
+	    Fix incorrect typemaps being used for a symbol within a templated type, eg:
+            A<int>::value_type would incorrectly use a typemap for type A.

 	    [Tcl] Fix variable declarations in middle of blocks which isn't
 	    permitted in C90 (issue probably introduced in 2.0.3 by patch #3224663).
