is shown) not only character mode.

(debug): In backtrace, show the renaming pairs for unbound
variables (up_p_a_pairs) if they are present.
* debug.h (debug_begin): Renamed to debug_frame.
* eval.c (eval): Wrap debug_begin/debug_end around function dispatch,
so TXR Lisp functions are included in backtraces.

Pass in evaluated args, not the original ones.

* unwind.h (struct uw_debug): Member bindings renamed to env.

and used for next/step/finish stepping.
* Makefile (OBJS): debug.o moved to OBJS-y or OBJS-.
(OBJS-y, OBJS-): New variables.
$(PROG): Depends on OBJS-y also.
clean: clean $(OBJS-y).
depend: include $(OBJS-y) in dependency generation.
* configure: Underscores and dashes are interchangeable in
configure variables.
(yaccname_given, yacc_given): Default value is y, not yes.
(debug_support): New config variable.
(CONFIG_DEBUG_SUPPORT): New config.h symbol.
* debug.c (debug_depth): New global variable.
(debug_block_s): New symbol variable.
(next_depth): New static variable.
(debug): Renamed some commands. Introduced separate next, step
and finish.
(debug_init): debug_block_s initialized.
* debug.h (debug_depth, debug_block_s): Declared.
(debug_enter, debug_leave, debug_return): New macros.
(debug_check, debug_init): Conditionally defined based on
if this is a debug build.
* dep.mk: Regenerated.
* eval.c (eval): Instrumented with debug_enter, debug_leave,
debug_return.
* match.c (match_line, v_fun, match_files): Likewise.

than nil, otherwise hitting enter tries to repeat the nil command.
(show_bindings): New function. Prints all levels of bindings.
(debug): Flip the corresponding print flags after printing the current
form or data, so they are not printed for every prompt.
On EOF from standard input, substitute the q command.
If enter is hit and there is no last command, just re-print the prompt.
The v command uses show_bindings to dump the environment.
* eval.c (eval): When calling debug_check, pass the env objects, rather
than the bindings it contains.

Enter stopped working. This was broken by recent bugfixes in the
string splitting functions, which introduced a semantics change.
* eval.c (flip_s, vecref_s): New symbol variables.
(op_modplace): New places (vecref ...) and (flip ...). Bugfix: dec
operator was incrementing.
(expand_place): Handle vecref and flip. Bugfix: pop has no
third argument and so is now handled by the same case as flip.
Bugfix: if a modify form has no third argument, then do not
resynthesize it with a nil third argument.
(eval_init): Initialize new symbol variables.
Register new flip operator. Register new list_vectory function
as intrinsic.
* lib.c (rplacd): When modifying the cdr field of a lazy cons,
then lapse the lazy function to nil! This is needed by user-defined
lazy conses, and it makes sense to do it this way rather than
put in some explicit interface.
(list_vector): New function.
* lib.h (list_vector): Declared.

the sequencing! Making it an inline function broke the tests.
But we can't have multiple evaluation either, so it's going to use
a temporary lexical variable.
(uses_or2): Macro which declares the lexical variable needed by or2.
* debug.c (debug): add uses_or2.
* eval.c (eval_intrinsic, op_modplace): Likewise.

to set up a debug frame for backtracing.
(match_line, match_files): Call debug_check to give debugger a chance
to instrument call.
(v_fun): Use debug_begin and debug_end macros to set up a debug frame
for backtracing. Call debug_check to give debugger a chance to
instrument call.
