+       * eval.c (setup_frame): Change all uses of do_optimize to be
+       a boolean check instead of a test > 1.
+       * awkgram.y: Ditto.
+       (optimize_assignment): Remove check against do_optimize since
+       it was inited to true anyway.

        * re.c (resetup): Add a comment about the joy of syntax bits.

-
-       Review all FIXME and TODO comments
-
-       Fix all *assoc_lookup() = xxx  calls.
-
-       Make GAWKDEBUG pass the test suite.
-
-       Make fflush() and fflush("") both flush all files, as in BWK awk.
-
-       In gawkapi.c - review switch statements and use of default.
