+
+       Miscellaneous code readability improvements.
+
+       * src/reader.c (reader): Move %define front-end variable
+       defaults and checking into...
+       (prepare_percent_define_front_end_variables): ... this new
+       function.
+
+       * src/scan-gram.l (INITIAL): For consistency with string
+       literals, don't store open quote on character literal.  It's
+       discarded before returning anyway.
+       (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
+       Make length test more readable, and make the character stored
+       for an empty literal more obvious while consistent with the
+       previous behavior.
+
+       * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
+       USER_NUMBER_HAS_STRING_ALIAS throughout.
+       * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
+       that is repeated in symtab.h.  Improve argument names to make it
+       clear which side of the symbol-string alias pair is which.
+       (symbol_check_alias_consistency): Improve local variable names
+       for the same purpose.
+       * src/symtab.h (struct symbol): Make comments about aliases
+       clearer.
+       (symbol_make_alias): Improve comments and argument name.
+       * src/output.c (token_definitions_output): Update for rename to
+       USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
+
+2009-08-08  Alex Rozenman  <rozenman@gmail.com>
+
+       Convert "misleading reference" messages to warnings.
+       * src/scan-code.l: New function 'show_sub_messages', more
+       factoring.
+       * tests/named-ref.at: Adjust tests.
