* libguile/goops.c (DEFVAR): Remove this helper macro, replacing its
uses with scm_module_define, but without scm_module_export.
(create_basic_classes, scm_init_goops_builtins): Update callers.
(make_class_from_template, make_class_from_symbol): Change to not
define variables for classes. This affects ports, struct classes, and
smob classes.
* module/oop/goops.scm: Explicitly list our exports, so there is no more
trickery happening in C.
(find-subclass): Private helper to grub the class hierarchy, so we can
define bindings for smobs, ports, etc. Use to define the classes that
goops.c used to define -- probably a subset, but it's better to have
them listed.
* libguile/threads.c (on_thread_exit): Clear `t->guile_mode' upon
entry. This fixes a bug whereby `t->base' would be incorrect for
canceled threads, leading to a misdiagnosed VM stack overflow.
See <http://lists.gnu.org/archive/html/bug-guile/2011-06/msg00068.html>
for details.
(scm_leave_guile_cleanup): Remove because it's unused.
* libguile/load.c (canonical_to_suffix, scm_primitive_load_path):
* module/ice-9/boot-9.scm (load-in-vicinity):
* module/system/base/compile.scm (compiled-file-name): If the canonical
path of a file is a DOS-style path with a drive letter, turn it into a
path suffix it by removing the colon and prefixing a "/".
Inspired by a patch from Jan Nieuwenhuizen.
* doc/ref/guile.texi (Programming in Scheme):
* doc/ref/scheme-scripts.texi (Guile Scripting): Moved "Invoking Guile"
to its own file.
* doc/ref/guile-invoke.texi (Invoking Guile): Initial revision. This
file contains the former section "Invoking Guile" that was included in
the chapter "Programming in Scheme" as a subsection named
"Command-line Options." It also includes a new subsection "Environment
Variables," which describes those variables that can be set in the
operating system before Guile is started and which affect Guile's
run-time behavior.

* libguile/threads.c (fat_mutex_lock): In the `m->level == 0' case,
release M's lock before taking T's `admin_mutex'.
* configure.ac: Add a check for GC_get_suspend_signal().
* libguile/scmsigs.c (GC_get_suspend_signal): Define a fallback
implementation if one isn't available.
(signal_delivery_thread): Unmask the suspend signal so that GC can
stop the world. Fixes test-pthread-create on libgc 7.1 and earlier.
Thanks to Frank Terbeck <ft@bewatermyfriend.org> for the report.
* module/ice-9/psyntax.scm (syntax-case): enabled the use of a
general last cdr instead of just '() in matching with both
a ellipsis (p ...) and a last rest pattern (. q)
* module/ice-9/psyntax-pp.scm: Regenerated.
This fixes warnings saying "this decimal constant is unsigned only in
ISO C90".
* test-suite/standalone/test-ffi-lib.c (test_ffi_u32_, test_ffi_u32_u8,
test_ffi_u32_s64, test_ffi_s64_s64, test_ffi_u64_u8,
test_ffi_u64_s64): Mark constants as unsigned.
* configure.ac: Remove code that determines the values of the `iconveh_'
constants. Use `GUILE_UNISTRING_ICONVEH_VALUES'. instead.
* acinclude.m4 (GUILE_UNISTRING_CONSTANT,
GUILE_UNISTRING_ICONVEH_VALUES): New macros.
* module/system/base/language.scm (current-language): Default to 'scheme
here, rather than relying on *current-language* always being bound.
Thanks to 亚光唐 <texnician@gmail.com> for the report.
* module/language/tree-il/primitives.scm (+, *, cons*): In the case of
just one argument (the identity case), expand to (values x) instead of
just x. Fixes values truncation in that case.
(values): Likewise remove (values x) -> x translation, as the compiler
will do it for us, and this fixes (values (values 1 2)).
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Handle
`values' in a push context here.
* test-suite/tests/tree-il.test ("values"): Add some tests.
http://savannah.gnu.org/bugs/?33362
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Rename
from flatten, as it really just takes a particular case. Instead of
iteratively compiling lambda cases through `comp', tail-call through
flatten-lambda-case. This allows code to see which case it's being
compiled in. Take advantage of that to limit the self-tail-call
optimization to self-calls to the same case -- otherwise we might be
jumping to a label without having reserved the right number of
locals.
(flatten-lambda): Adapt the caller.
* test-suite/tests/compiler.test ("case-lambda"): Add a test.
* module/ice-9/psyntax.scm (generate-temporaries): Give temporaries the
current module, so that they may be bound at the top level.
* module/ice-9/psyntax-pp.scm: Regenerate.
* libguile/strings.c (scm_i_allocate_string_pointers): Encode strings
using the current locale. Previously, Latin-1 was used. Indirectly,
this affects the encoding of strings in `system*', `execl', `execlp',
`execle', `environ', and `dynamic-args-call'.
(scm_makfromstrs): In header comment, clarify that the C strings are
interpreted according to the current locale encoding.
* NEWS: Add NEWS entry.
Added pipe2 and open modules, to get O_CLOEXEC.
* libguile/Makefile.am (guile_filter_doc_snarfage$(EXEEXT)): Add gnulib
here, in the native build case, for rpl_fflush if needed.
foo
* libguile/threads.h:
* libguile/threads.c (scm_i_reset_fluid): New internal function, resets
the binding of a fluid for all threads. Needed for fluid GC.
* libguile/fluids.c (new_fluid): Call scm_i_reset_fluid here.
* doc/ref/api-control.texi (Prompt Primitives): Break call-with-prompt
and abort-to-prompt out into a subsubsection.
(Shift and Reset): New subsubsection.
* test-suite/tests/weaks.test: Add tests.
* libguile/hashtab.c (scm_hash_fn_set_x): Fix updates to weak-value hash
tables to not deadlock inside the alloc lock.
* doc/ref/scheme-using.texi (Using Guile Tools): Add a footnote
mentioning that `guild' used to be `guile-tools'.
* doc/ref/tools.texi (Executable Modules): Nitpicks.
* libguile/expand.h:
* module/language/tree-il.scm: Rename "sequence" to "seq", and instead
of taking a list of expressions, take a head and a tail.
* module/language/tree-il/analyze.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/fix-letrec.scm:
* module/language/tree-il/spec.scm:
* module/language/elisp/compile-tree-il.scm:
* module/ice-9/psyntax.scm:
* module/ice-9/psyntax-pp.scm:
* module/ice-9/eval.scm:
* libguile/memoize.h:
* libguile/memoize.c:
* libguile/expand.c:
* libguile/eval.c: Adapt to the new seq format.
* libguile/_scm.h (SCM_OBJCODE_ENDIANNESS_OFFSET):
(SCM_OBJCODE_WORD_SIZE_OFFSET): New defines.
* libguile/objcodes.c (scm_write_objcode): Use target-endianness and
target-word-size when writing the objcode cookie.
