 To do (not necessarily in this order):
 
-- Fix Makefile.am to build gawk as a stub calling into a shared library.
-  This will allow extensions to work on Cygwin and Mingw.
+- Figure out how to support xgawk on platforms such as Cygwin where a DLL
+  cannot be linked with unresolved references.  There are currently 3
+  possible solutions:
+    1. Restructure gawk as a stub calling into a shared library.
+    2. Move a subset of gawk interfaces into a shared library that can be
+       called by extensions.
+    3. Change the interface between gawk and extensions so that gawk will
+       pass a pointer to a structure into dlload that contains the addresses
+       of all variables and functions to which the extension may need access.
+
+- Add valgrind-noleak target.
 
 - Enable default ".awk" search in io.c:find_source().  The simple change
   is to add this code inline in io.c:
