+
+       * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
+       full stderr, and strip it according to the bison options, instead
+       of composing the error message from different bits.
+       This makes it easier to check for several error messages.
+       Adjust all the invocations.
+       Add an invocation exercising the error token.
+       Add an invocation demonstrating a stupid error message.
+       (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
+       Adjust the tests.
+       Error message are for stderr, not stdout.

+
+       * src/gram.h, src/gram.c (error_token_number): Remove, use
+       errtoken->number.
+       * src/reader.c (reader): Don't specify the user token number (2)
+       for $undefined, as it uselessly prevents using it.
+       * src/gram.h (token_number_t): Move to...
+       * src/symtab.h: here.
+       (state_t.number): Is a token_number_t.
+       * src/print.c, src/reader.c: Use undeftoken->number instead of
+       hard coded 2.
+       (Even though this 2 is not the same as above: the number of the
+       undeftoken remains being 2, it is its user token number which
+       might not be 2).
+       * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
+       `user_token_number_max'.
+       Output `undef_token_number'.
+       * data/bison.simple, data/bison.c++: Use them.
+       Be sure to map invalid yylex return values to
+       `undef_token_number'.  This saves us from gratuitous SEGV.
+
+       * tests/conflicts.at (Solved SR Conflicts)
+       (Unresolved SR Conflicts): Adjust.
+       * tests/regression.at (Web2c Actions): Adjust.

+
+       * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/.
+       Adding #line.
+       Remove the duplicate `typedefs'.
+       (RhsNumberType): Fix the declaration and various other typos.
+       Use __ofile__.
+       * data/bison.simple: Use __ofile__.
+       * src/scan-skel.l: Handle __ofile__.
+
+2002-04-08  Akim Demaille  <akim@epita.fr>
+
+       * src/gram.h (item_number_t): New, the type of item numbers in
+       RITEM.  Note that it must be able to code symbol numbers as
+       positive number, and the negation of rule numbers as negative
+       numbers.
+       Adjust all dependencies (pretty many).
+       * src/reduce.c (rule): Remove this `short *' pointer: use
+       item_number_t.
+       * src/system.h (MINSHORT, MAXSHORT): Remove.
+       Include `limits.h'.
+       Adjust dependencies to using SHRT_MAX and SHRT_MIN.
+       (shortcpy): Remove.
+       (MAXTABLE): Move to...
+       * src/output.c (MAXTABLE): here.
+       (prepare_rules): Use output_int_table to output rhs.
+       * data/bison.simple, data/bison.c++: Adjust.
+       * tests/torture.at (Big triangle): Move the limit from 254 to
+       500.
+       * tests/regression.at (Web2c Actions): Ajust.
+
+       Trying with bigger grammars shows various phenomena: at 3000 (28Mb
+       of grammar file) bison is killed by my system, at 2000 (12Mb) bison
+       passes, but produces negative #line number, once fixed, GCC is
+       killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
+       C), it passes.
+       * src/state.h (state_h): Code input lines on ints, not shorts.
+
+2002-04-08  Akim Demaille  <akim@epita.fr>
+
+       * src/reduce.c (reduce_grammar): First reduce the nonterminals,
+       and then the grammar.

+
+       * src/system.h: No longer using strndup.

        * src/muscle_tab.h (MUSCLE_INSERT_LONG_INT): New.
