+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.c (augment_automaton): Now that all states have shifts,
+	merge the two cases addition shifts to the initial state.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/lalr.c (set_state_table): Move to...
+	* src/LR0.c: here.
+	* src/lalr.c (lalr): Don't call it...
+	* src/LR0.c (generate_states): do it.
+	* src/LR0.h (first_state): Remove, only the table is used.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.h (first_shift, first_reduction): Remove.
+	* src/lalr.c: Don't use first_shift: find shifts through the
+	states.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.c: Attach shifts to states as soon as they are
+	computed.
+	* src/lalr.c (set_state_table): Instead of assigning shifts to
+	state, just assert that the mapping was properly done.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.c (insert_start_shift): Rename as...
+	(insert_start_shifting_state): this.
+	(insert_eof_shifting_state, insert_accepting_state): New.
+	(augment_automaton): Adjust.
+	Better locality of the variables.
+	When looking if the start_symbol is shifted from the initial
+	state, using `while (... symbol != start_symbol ...)' sounds
+	better than `while (... symbol < start_symbol ...)': If fail
+	to see how the order between symbols could be relevant!
+
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/getargs.h: Don't declare `spec_name_prefix' and
+	`spec_file_prefix', declared by src/files.h.
+	* src/files.c, src/files.h: Default for spec_name_prefix is "yy".
+	* src/muscle_tab.c (muscle_init): Default prefix to NULL.
+	* src/output.c (prepare): Adjust.
+	* src/reader.c (symbols_output): Likewise.
+	* src/vmsgetargs.c: Vaguely adjust, but who cares?
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/muscle_tab.c (muscle_init): NULL is a better default than
+	`"0"'.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/reader.c (reader): Calling symbols_output once is enough.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	Now that states have a complete set of members, the linked list of
+	reductions is useless: just fill directly the state's reductions
+	member.
+
+	* src/state.h (struct reductions): Remove member `number' and
+	`next'.
+	* src/LR0.c (first_reduction, last_reduction): Remove.
+	(save_reductions): Don't link the new reductions, store them in
+	this_state.
+	* src/lalr.c (set_state_table): No need to attach reductions to
+	states, it's already done.
+	* src/output.c (output_actions): No longer free the shifts, then
+	the reductions, then the states: free all the states and their
+	members.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/options.c (OPTN, DRTV, BOTH): New.
+	(option_table): Use them.
+
+	
+	* src/muscle_tab.c: Don't include xalloc.h and string.h: that's
+	the job of system.h.
+	* src/options.c: Don't include stdio.h and xalloc.h for the same
+	reasons.
+
+	
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	* src/output.c (output, prepare): Make sure the values of the
+	muscles `action' and `prologue' are 0-terminated.
+
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+	Clean up GCC warnings.
+
+	* src/reader.c (copy_action): `buf' is not used.
+	(parse_skel_decl): Be static.
+	* src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
+	* src/options.h (create_long_option_table): Have a real prototype.
+	* lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
+	(hash_delete_at): Return const void *.
+	Adjust casts to preserve the const.
