+       Use "enum" for integral constants.
+       This is just nicer to read, I observed no speedup.

+       Change the handling of the symbols in the skeletons.
+       Before we were using tables which lines were the symbols and which
+       columns were things like number, tag, type-name etc.  It is was
+       difficult to extend: each time a column was added, all the numbers had
+       to be updated (you asked for colon $2, not for "tag").  Also, it was
+       hard to filter these tables when only a subset of the symbols (say the
+       tokens, or the nterms, or the tokens that have and external number
+       *and* a type-name) was of interest.
+       
+       Now instead of monolithic tables, we define one macro per cell.  For
+       instance "b4_symbol(0, tag)" is a macro name which contents is
+       self-decriptive.  The macro "b4_symbol" provides easier access to
+       these cells.
+       
+       * src/output.c (type_names_output): Remove.
+       (symbol_numbers_output, symbol_definitions_output): New.
+       (muscles_output): Call them.
+       (prepare_symbols): Define b4_symbols_number.
