* libguile/deprecated.c (scm_uniform_vector_read_x,
scm_uniform_vector-write): Account for optional arguments. Make sure
the former always returns an integer.
* libguile/deprecated.h (scm_uniform_vector_read_x,
scm_uniform_vector_write, scm_uniform_array_read_x,
scm_uniform_array_write): Mark as `SCM_DEPRECATED'.
* libguile/posix.c (scm_utime): Use "#ifdef HAVE_UTIMENSAT", not "#if
HAVE_UTIMENSAT". Fix GCC warning around call to utimensat(2):
"passing argument 3 of 'utimensat' from incompatible pointer type".
* test-suite/tests/posix.test ("utime"): New test prefix.
When compiled with SCM_ENABLE_ELISP undefined, the reader options
macros SCM_R6RS_ESCAPES_P and SCM_SQUARE_BRACKETS_P point past
the end of the scm_read_opts struct.
*libguile/private-options.h (SCM_R6RS_ESCAPES_P) [!SCM_ENABLE_ELISP]: modified
(SCM_SQUARE_BRACKETS_P) [!SCM_ENABLE_ELISP]: modified
(SCM_N_READ_OPTIONS): modified
* module/scripts/snarf-check-and-output-texi.scm
(process-multiline-directive): Be more accepting of source location
markers in the preprocessed source, by adding a couple cases in which
they can appear. Not foolproof, but it does adapt to what new GCCs are
putting out (e.g. cpp (GCC) 4.4.2 20091222 (Red Hat 4.4.2-20)).
* libguile/posix.h:
* libguile/posix.c (scm_utime): Add optional nanosecond arguments. This
is an incompatible change on the C level, but it's unlikely people are
using this POSIX wrapper function, because they would just use the
POSIX function directly. Hopefully, anyway.
* module/system/base/compile.scm (call-with-output-file/atomic):
Propagate source timestamps to targets with nanosecond precision, if
available. Fixes build on systems with ext4 filesystems.
* libguile/filesys.c (scm_stat2scm):
* module/ice-9/posix.scm (stat:atimensec, stat:mtimensec)
(stat:ctimensec): Add three new elements to Scheme stat structures,
for nanosecond-level timestamps.
* configure.ac: Add checks for utimensat, and for nanosecond fields in
struct stat. We should switch to using Gnulib things for these,
though.
* doc/ref/posix.texi (File System): Add documentation for utime's
additional arguments, and nanosecond stat timestamp accessors.
* libguile/private-options.h:
* libguile/read.c (scm_read_opts, SCM_SQUARE_BRACKETS_P): Add an option
for treating [ and ] as parentheses, on by default. Note that this
makes them delimiters also, so [ and ] cannot appear in a symbol name,
with this read option on.
(scm_read_sexp): If we start with [, we end with ].
(scm_read_expression): Add case for [.
* module/statprof.scm: Use VM modules, instead of using @ hacks.
(statprof): New public export, a functional interface to the profiler.
(profile-signal-handler, count-call, statprof-start, statprof-stop):
Fix call counting with the VM.
(statprof-call-data->stats): Hack around a case in which a call could
be sampled but not counted, if you get my drift.
(procedure=?): Update for current API.
(with-statprof): Use `statprof'.
* module/system/repl/command.scm (profile): Use the `statprof'
procedural interface.
* module/ice-9/syncase.scm: Export datum->syntax-object and
syntax-object->datum as aliases of datum->syntax and syntax->datum.
Thanks to Daniel Llorens del Río for the suggestion.
* libguile/vm-engine.h (RUN_HOOK1): Add some machinery whereby a hook
can push an arg on the stack, run the hook, then drop the value.
(RETURN_HOOK): Use it here, so we push the number of returned values.
* libguile/vm-i-system.c (return, return-values): Adapt to RETURN_HOOK
changes.
* module/system/vm/trace.scm (vm-trace): Change to just export the one
procedure, vm-trace. This way it's threadsafe and more robust. Also
refactor to not print any of Guile's internal bits. Hopefully Neil
will be happier :)
* module/system/repl/command.scm (option): Adapt to removal of
vm-trace-on! and vm-trace-off!, as those are unlikely to DTRT.
* README: Don't suggest setting vars before running configure.
Instead, suggest specifying them on the configure command-line.

When the reader option 'r6rs-hex-escapes is enabled, the \uNNNN and
\UNNNNNN string escape sequences should be disabled.
* libguile/read.c (scm_read_string): added checks for SCM_R6RS_ESCAPES_P
* test-suite/tests/reader.test (r6rs-hex-escapes): new tests
* test-suite/tests/chars.test (R6RS Hex escapes): remove tests by reverting
to previous version
* test-suite/tests/strings.test (R6RS Hex escapes): remove tests by
reverting to previous version
This adds a reader option 'r6rs-hex-escapes that modifies the
behavior of numeric escapes in characters and strings. When enabled,
variable-length character hex escapes (#\xNNN) are allowed and become
the default output format for numerically-escaped characters. Also,
string hex escapes switch to a semicolon terminated hex escape (\xNNNN;).
* libguile/print.c (PRINT_CHAR_ESCAPE): new macro
(iprin1): use new macro PRINT_CHAR_ESCAPE
* libguile/private-options.h (SCM_R6RS_ESCAPES_P): new #define
* libguile/read.c (scm_read_opts): add new option r6rs-hex-escapes
(SCM_READ_HEX_ESCAPE): modify to take a terminator parameter
(scm_read_string): parse R6RS hex string escapes
(scm_read_character): parse R6RS hex character escapes
* test-suite/tests/chars.test (with-read-options): new procedure
(R6RS hex escapes): new tests
* test-suite/tests/strings.test (with-read-options): new procedure
(R6RS hex escapes): new tests
* module/system/vm/program.scm (program-arguments-alist): Rename from
program-arguments, a name shadowed by features.c
(arglist->arguments-alist, arity->arguments-alist)
(arguments-alist->lambda-list, program-lambda-list, write-program):
Adapt callers.
* module/system/vm/frame.scm (frame-lookup-binding): Return #f if the
binding is not found, not an error.
(frame-binding-set!, frame-binding-ref): Adapt to error appropriately.
(frame-arguments): Dispatch to frame-call-representation.
(frame-call-representation): Refactor a bit.
* module/ice-9/session.scm (procedure-arguments): Adapt to
program-arguments name change.
* module/texinfo/reflection.scm (get-proc-args): Refactor to actually
work with VM procedures.
* libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): Add a width parameter,
indicating the number of sizeof(ctype) entries comprised by one
element of the uniform; normally 1, but 2 for c32 and c64.
* libguile/arrays.h:
* libguile/arrays.c (scm_from_contiguous_array): New public function,
like scm_from_contiguous_typed_array but for arrays of generic Scheme
values.
* libguile/vm-i-scheme.c (make-struct): Sync regs before making the
struct, so if we get a GC the regs are on the heap.
(make-array): New instruction, makes an generic (untyped) Scheme
array.
* module/language/glil/compile-assembly.scm (dump-object): Correctly
compile arrays.
* module/ice-9/boot-9.scm (export, re-export): Evaluate at compile-time
in addition to load/eval.
* test-suite/tests/tree-il.test ("warnings")["unused-toplevel"]("unused
but define-public"): Remove throw to `unresolved'.
* module/ice-9/boot-9.scm: Load `deprecated.scm' with
`resolve-interface' instead of `primitive-load-path'.
* module/ice-9/deprecated.scm: Turned into a module, `(ice-9
deprecated)'.
