* module/system/vm/traps.scm: Fix a comment.
* module/system/vm/trap-state.scm (<trap-state>): Add next-ephemeral-idx
slot.
(wrapper-at-index): Use eqv? instead of = to avoid type errors in user
inputs.
(next-ephemeral-index!, ephemeral-handler-for-index): New functions,
allocate ephemeral trap ids for functions to be called only once.
(add-trap-at-frame-finish!): New export, traps when a frame finishes.
* module/system/vm/frame.scm (frame-return-values): New exported
function, gives the return values for a frame.
* module/system/vm/trace.scm: Remove frame-return-values from here.
* module/system/repl/error-handling.scm (call-with-error-handling): If
the given index is false, assume this was an ephemeral trap, and don't
print a welcome message or reference the trap by index.
* doc/ref/goops.texi (Generic Functions and Accessors): Renamed from
`Creating Generic Functions'. Explain what an accessor is.
(Basic Generic Function Creation): Clarify the point of the text
about generics having short names.
* module/system/vm/traps.scm (trap-at-procedure-ip-in-range): Rework not
to call the handler when returning to a frame that was already
entered. So now breaking at foo.scm:1234 doesn't break when returning
to that line.
* module/srfi/srfi-45.scm: New file, containing the reference implementation of
SRFI 45, slightly adapted to use SRFI-9.
* module/Makefile.am (SRFI_SOURCES): Added srfi/srfi-45.scm.
* test-suite/tests/srfi-45.test: New file.
* test-suite/Makefile.am (SCM_TESTS): Add tests/srfi-45.test.
* doc/ref/srfi-modules.texi (SRFI-45): New node and subsection;
essentially a shortended transcript of the SRFI-45 specification.
* module/srfi/srfi-42/ec.scm: New file; reference implementation of
SRFI 42.
* module/srfi/srfi-42.scm: New file; module for SRFI 42.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-42.scm.
(NOCOMP_SOURCES): Add srfi/srfi-42/ec.scm.
* test-suite/tests/srfi-42.test: New file; test suite for SRFI 42.
* test-suite/Makefile.am: SCM_TESTS: Add tests/srfi-42.test.
* module/system/vm/traps.scm (trap-in-procedure): If we are
(re-)entering the procedure from a return, call the enter-proc with
the returnee, not the returner.
(in-range?): Tighten up a bit.
(program-sources-before-retire): New helper, like program-sources but
indexed before instructions are retired instead of after.
(program-sources-by-line): Use program-sources-before-retire so that
we can break on instructions by source line *before* those
instructions are executed.
As module/oop/goops/stklos.scm, the available compatibility is
superficial only, so it isn't worth documenting.
* doc/ref/goops.texi (STKlos Compatibility): Removed.
* doc/ref/goops.texi (Defining New Classes): Move `Class Definition
Internals' and `Customizing Class Definition' notes to the
metaobject protocol section.
* module/system/vm/trap-state.scm (add-trap-at-source-location!):
* module/system/vm/traps.scm (trap-at-source-location): Rename "line"
argument to "user-line", indicating that the line is one-based instead
of zero-based. Decrement the line before handing off to
source-closures-or-procedures and source->ip-range.

procedure, returns a 1-indexed line, suitable for presentation to a
user.

* libguile/stackchk.h: Include private-options.h if we are building
guile.
* libguile/vm.c (scm_c_vm_run): Check for C stack overflow before
entering the engine.
Fixes an error when running ./configure:
./configure: line 31873: text: command not found
* configure.ac: Change "text" to "test", in libltdl-related code.
* libguile/eval.c:
* libguile/debug.c (scm_debug_opts): Move here, from eval.c. Change
SCM_BACKTRACE_P to 1, initially.
* libguile/private-options.h: Make all options vars private.
* doc/ref/api-debug.texi (Programmatic Error Handling): Rename from
"Debug on Error". Reorganize subsections according to when the error
is handled.
* doc/ref/api-options.texi: Adapt xref.
* doc/ref/api-debug.texi (Debug on Error): Move debug options here (for
now). Leave debug-options-interface undocumented.
* doc/ref/api-options.texi (Runtime Options): Remove debug options. Link
to the sections where the options documentation is now. Update the
options example transcript.
* doc/ref/api-options.texi (Debugger options):
* doc/ref/repl-modules.texi (Readline Options): Use 'help instead of
'full (they are entirely equivalent right now). Update output to show
options in the right order.
* doc/ref/api-evaluation.texi (Scheme Read): Fold all reader options
docs into this section. Undocument read-options-interface.
(Scheme Write): New section for `write' and `display', and the print
options. print-enable/print-disable are not documented, as there are
no boolean print options. print-options-interface is likewise
undocumented.
* doc/ref/api-options.texi: Remove discussion of options in
general. Move read options to Scheme Read, and print options to Scheme
Write.
* doc/ref/api-io.texi (Reading): Link to Scheme Read.
(Writing): Move write and display to Scheme Write, and link there.
* doc/ref/srfi-modules.texi:
* doc/ref/api-debug.texi:
* doc/ref/api-data.texi: Update xrefs.
* libguile/private-options.h (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P):
* libguile/read.c (scm_read_opts): Remove unused elisp-vectors option,
and the elisp-strings option (which allowed \( and \) escapes in
strings).
(scm_read_string): Remove the elisp-strings case.
* doc/ref/api-options.texi (Reader options): Update, and update wording
of the case-insensitive bit.
* libguile/frames.h:
* libguile/frames.c (scm_frame_stack_pointer): New function.
* module/system/repl/debug.scm (print-registers): New function, prints
out registers.
* module/system/repl/command.scm (registers): New debugging
meta-command.
(inspect): Not a stack-command, a normal meta-command.
* libguile/script.c (scm_compile_shell_switches): Select the debugging
VM in the cases that we previously would select deval -- when running
interactively without --no-debug, or otherwise with --debug.
* libguile/vm.c: Default to the regular engine.
(scm_c_set_vm_engine_x): Remove requirement for the VM to have no
pending computations.
