+      Some additional commits from Alan reduce this FLASH size by
+      about another kilobyte.  That changes:  (1) disable stack
+      dumping on assertions,and (2) make some FLASH data structures
+      smaller.
+
+      Almost 2Kb of the remaining size is due to some arithmetic
+      functions drawn from libgcc.a.  Alan is currently looking
+      into ways to eliminate thost libgcc.a objects from the link.
