* module/system/repl/command.scm:
* module/system/repl/debug.scm (terminal-width): Move terminal-width
here, make it thread-local, and export it.
(print-locals, print-frame, print-frames): Default width to
terminal-width.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
`report' and `backtrace' on-error handlers.
* module/system/repl/common.scm (repl-default-options): Add on-error
REPL option, defaulting to `debug', but which may be changed.
* module/system/repl/repl.scm (run-repl): Pass the #:on-error REPL
option to call-with-error-handling.
* libguile/arrays.c (scm_i_read_array):
* libguile/backtrace.c (display_backtrace_body):
* libguile/filesys.c (scm_readdir)
* libguile/i18n.c (chr_to_case):
* libguile/ports.c (register_finalizer_for_port):
* libguile/posix.c (scm_nice):
* libguile/stacks.c (scm_make_stack): Clean up a number of
set-but-unused vars. Thanks to Douglas Mencken for the report.
* libguile/numbers.c (scm_log, scm_exp): Fix a few #if cases that should
be #ifdef.
* libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
functions, useful to pass and receive SCM values to and from foreign
functions.
* module/system/foreign.scm: Export the new functions.
* doc/ref/api-foreign.texi (Foreign Variables): Add docs.
* test-suite/tests/foreign.test ("pointer<->scm"): Tests.
* test-suite/tests/control.test: Use c&e tests for most test blocks.
Note that this did not catch the recent bug.
("reified continuations"): Add a new test for capturing partial
continuations containing pending call frames. Before these would
contain dynamic links pointing out of the continuation segment, which
would not be relocated; now, the dynamic links are only made when the
frames are activated.
Thanks to Wolfgang J Moeller for the bug report and test case.
* libguile/vm-i-system.c (new-frame): Though it was appealing to set the
dynamic link here on the incomplete frame, we no longer do that, for
the reasons mentioned in the code.
(call, mv-call): Adapt to set the frame's dynamic link.
* libguile/vm-engine.c (vm_engine): Don't set dynamic link here, even
for boot program.
* libguile/frames.c (scm_frame_num_locals, scm_frame_local_ref)
(scm_frame_local_set_x): Fix up not-yet-active frame detection.
* module/rnrs/io/ports.scm (transcoder-eol-style)
(transcoder-error-handling-mode): Export these.
(textual-port?): Implement this procedure and export it.
* module/rnrs.scm: Export these here as well.
* module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
(binary-port?): Treat only ports without an encoding as binary ports,
add docstring.
(standard-input-port, standard-output-port, standard-error-port):
Ensure these are created without an encoding.
(eol-style): Add `none' as enumeration member.
(native-eol-style): Switch to `none' from `lf'.
* test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
(8.2.10 Output ports): Test binary-ness of `standard-input-port',
`standard-output-port' and `standard-error-port'.
(8.2.6 Input and output ports): Add test for `port-transcoder'.

* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!'
in C for efficiency.
* libguile/r6rs-ports.h: Add prototype for this function.
* module/ice-9/binary-ports.scm: Export `get-string-n!'.
* module/rnrs/io/ports.scm (get-string-n): Implement based on
`get-string-n!'.
Export both `get-string-n!' and `get-string-n'.
* module/rnrs.scm: Also export these.
* test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few
tests for `get-string-n' and `get-string-n!'.

* module/srfi/srfi-9.scm (define-inlinable): When inlining, evaluate the
arguments only once. Reported by Andreas Rottmann; thanks to Andy
Wingo for the elegant solution.
* test-suite/tests/srfi-9.test ("side-effecting arguments"): New test
prefix.
* libguile/init.c (stream_body, scm_standard_stream_to_port): Don't name
stdin, stdout, and stderr -- at least not as strings. That confuses
any code which tries to treat port-filename as a real filename, like
the syntax expander, or the `load' procedure/macro. Also this
behavior matches the docs now.
This updates Gnulib to v0.0-4951-g6ff7b70.
* m4/gnulib-cache.m4: Add floor, ceil, frexp, and ldexp. Add wchar as
an explicit dependency; it had been present as an indirect dependency
before, but no longer. Remove round, which I had requested earlier,
but turned out to be unnecessary.
* module/language/tree-il/fix-letrec.scm (partition-vars): Previously,
for letrec* we treated all unreferenced vars as complex, because of
orderings of effects that could arise in their definitions. But we
can actually keep simple and lambda vars as unreferenced, as their
initializers cannot cause side effects.
(fix-letrec!): Remove letrec* -> letrec code, as it's unneeded.
The expansion of `define-inlinable' contained an expression, which made
SRFI-9's `define-record-type' fail in non-toplevel contexts ("definition
used in expression context").
* module/srfi/srfi-9.scm (define-inlinable): Get rid of apparently
useless expression in the expansion, so the expansion yields only
definitions. At the same time, use a space in the generated names to
lessen the chances of name conflicts, also avoiding -Wunused-toplevel
warnings.
* test-suite/tests/srfi-9.test (non-toplevel): New test verifying that
`define-record-type' works in non-toplevel context as well.
* doc/ref/srfi-modules.texi (SRFI-9 - define-record-type): Add
subsubsection noting that Guile does not enforce top-levelness.

parameter from `str' to `name'.
* libguile/keywords.h: Add prototypes for new functions. Change formal
parameter of scm_from_locale_keyword* from `str' to `name'.
* doc/ref/api-data.texi: Document new functions. Remind users that
scm_from_locale_keyword should not be used when the name is a C string
constant. Change formal parameter from `str' to `name'.
* libguile/keywords.c (scm_from_latin1_keyword, scm_from_utf8_keyword):

scm_from_latin1_string, scm_from_utf8_string, and
scm_from_utf32_string. Remind readers that these functions should be
used to convert C string constants, and that scm_from_locale_string is
_not_ appropriate for that purpose.
(Symbol Primitives): Document scm_from_latin1_symbol and
scm_from_utf8_symbol. Remind readers that these functions should be
used when the specified names are C string constants, and that
scm_from_locale_symbol is _not_ appropriate for that purpose.
* doc/ref/api-data.texi (Conversion to/from C): Document
scm_from_latin1_string, scm_from_utf8_string, and
scm_from_utf32_string. Remind readers that these functions should be
used to convert C string constants, and that scm_from_locale_string is

scm_from_locale_symbol is _not_ appropriate for that purpose.
* module/ice-9/boot-9.scm (while): Report an error if `continue' is
passed one or more arguments. Previously, it would report an error if
`(continue arg rest ...)' was found within the `while', but not if
`continue' was found bare and later applied to one or more arguments,
e.g. `(apply continue (list arg rest ...))'.
* libguile/numbers.c (scm_quotient, scm_remainder, scm_modulo): Accept
inexact integers as well as exact ones, as required by the R5RS.
* test-suite/tests/numbers.test (quotient, remainder, modulo): Add tests.

* libguile/numbers.c: Update comments regarding GMP earlier than 4.2.
Remove speculations about versions of GMP that had not yet been
released when the comments were written. Replace them with facts that
are now known about the changes made in GMP 4.2.
* doc/ref/r6rs.texi (rnrs base): `(finite? x)' returns true iff x is
neither infinite nor a NaN. Previously, it stated that `finite?' was
the negation of `infinite?', which was incorrect because NaNs are
neither finite nor infinite. Combine description of 'nan?' with those
of `finite?' and `infinite?'.
Reported and fixed by Daniel Llorens <dll@bluewin.ch>.
* libguile/bytevectors.c (VALIDATE_REAL): Test for reals, not rationals.

(scm_private_ref, scm_c_public_ref, scm_c_private_ref)
(scm_public_variable, scm_private_variable, scm_c_public_variable)
(scm_c_private_variable): New helpers to get at variables and values
in modules.
* module/language/tree-il/fix-letrec.scm (fix-letrec!): When X is a
`letrec*' with only lambdas and simple expressions, analyze it as if
it were a `letrec'.
* test-suite/tests/tree-il.test ("letrec"): Add test for
`(letrec* (x y) (xx yy) ((const 1) (const 2)) (lexical y yy))'.
* libguile/symbols.c (default_gensym_prefix): New variable.

`scm_from_locale_stringn'.

caller's behalf.

scm_open_output_string): Pass SCM_BOOL_F as the STR argument of
`scm_mkstrport'.

* libguile/print.c (scm_simple_format): Likewise.
* libguile/strports.c (st_resize_port): Adjust to deal with OLD_STREAM
and NEW_STREAM as bytevectors.
(scm_mkstrport): Store a bytevector in the port's stream rather than a
string.
