Partial fix for <https://bugs.gnu.org/33044>.
Reported by Tom de Vries <tdevries@suse.de>.
Fix several instances of the mistake of using 'scm_from_locale_*' for C
strings that originally came from a C string literal. Change several
uses of 'scm_from_latin1_*' as well, to promote the practice of writing
code that works for arbitrary C string literals.
Also add missing years to the copyright notices of changed files, based
on the git history.

data type.
* libguile/syntax.c:
* libguile/syntax.h: New files.
* module/ice-9/boot-9.scm: Move new definitions to (system syntax
internal).
* module/system/syntax.scm (print-syntax): New helper.
* module/system/vm/assembler.scm (statically-allocatable?)
(intern-constant, link-data): Arrange to be able to write syntax
objects into images.
* module/language/cps/types.scm (&syntax): New type. Remove
&hash-table; it was never detected, an internal binding, and we need
the bit to avoid going into bignum territory.
* libguile/root.h:
* libguile/root.c: Remove these files.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_internal_cwdr, scm_call_with_dynamic_root)
(scm_dynamic_root, scm_apply_with_dynamic_root): Deprecate.
Remove all root.h usage, which was vestigial.
* module/ice-9/serialize.scm: Use (current-thread) instead
of (dynamic-root).
* libguile/__scm.h (SCM_TICK): Always define as scm_async_tick().
* libguile/error.c (scm_syserror, scm_syserror_msg):
* libguile/fports.c (fport_read, fport_write):
* libguile/_scm.h (SCM_SYSCALL): Replace SCM_ASYNC_TICK with
scm_async_tick ().
(SCM_ASYNC_TICK, SCM_ASYNC_TICK_WITH_CODE)
(SCM_ASYNC_TICK_WITH_GUARD_CODE): Remove internal definitions. We
inline into vm-engine.c, the only place where it matters.
* libguile/async.h:
* libguile/async.c (scm_async_tick, scm_i_setup_sleep):
(scm_i_reset_sleep, scm_system_async_mark_for_thread):
* libguile/threads.h (struct scm_thread_wake_data):
* libguile/threads.h (scm_i_thread):

Rewrite to use sequentially-consistent atomic references.
* libguile/atomics-internal.h (scm_atomic_set_pointer):
(scm_atomic_ref_pointer): New definitions.
* libguile/finalizers.c (queue_finalizer_async): We can allocate, so
just use scm_system_async_mark_for_thread instead of the set-cdr!
shenanigans.
* libguile/scmsigs.c (take_signal):
* libguile/gc.c (queue_after_gc_hook): Adapt to new asyncs mechanism.
Can't allocate but we're just manipulating the current thread when no
other threads are running so we should be good.
* libguile/vm-engine.c (VM_HANDLE_INTERRUPTS): Inline the async_tick
business.
* libguile/init.c (scm_i_init_guile): Initialize ports before
strports/fports, so that we have initialized the read/write
trampolines before making port types.
* libguile/load.c (scm_i_mirror_backslashes): New function.
(scm_init_load_path): Call it to produce MS-Windows file names
with forward slashes.
(FILE_NAME_SEPARATOR_STRING): Define as "/" on all platforms.
* libguile/load.h (scm_i_mirror_backslashes): Add prototype.
* libguile/init.c (scm_boot_guile): Call scm_i_mirror_backslashes
on argv[0].
* libguile/filesys.c (scm_getcwd): Call scm_i_mirror_backslashes
on the directory name returned by getcwd.
* test-suite/tests/ports.test ("file name separators"): New test.
* libguile/ports.c (scm_current_input_port, scm_current_output_port)
(scm_current_error_port): Fix declarations to C99.
(scm_current_warning_port, scm_set_current_warning_port): Rework to
use a C fluid, like scm_current_error_port.
(scm_init_ports): Initialize and define the warning port fluid.
* libguile/init.c (scm_init_standard_ports): Init the current warning
port.
* module/ice-9/boot-9.scm: Remove definitions for current-warning-port.
Instead, steal it from the boot objtable with port-parameterize!.
* libguile/gdb_interface.h:
* libguile/gdbint.c:
* libguile/gdbint.h: Remove. These were last modified significantly in
1997 and I think they are unused.
* libguile/guile.c: Remove use.
* libguile.h: Remove inclusion.
* libguile/Makefile.am: Remove reference.
* libguile/init.c: Remove use.
* libguile/fports.c (scm_open_file_with_encoding): New API function,
containing the code previously found in 'scm_open_file', but modified
to accept the new 'guess_encoding' and 'encoding' arguments.
(scm_open_file): Now just a simple wrapper that calls
'scm_open_file_with_encoding'.
(scm_i_open_file): New implementation of 'open-file' that accepts
keyword arguments '#:guess-encoding' and '#:encoding', and calls
'scm_open_file_with_encoding'.
(scm_init_fports_keywords): New initialization function that gets
called after keywords are initialized.
* libguile/fports.h (scm_open_file_with_encoding,
scm_init_fports_keywords): Add prototypes.
* libguile/init.c (scm_i_init_guile): Call 'scm_init_fports_keywords'.
* module/ice-9/boot-9.scm: Add enhanced versions of 'open-input-file',
'open-output-file', 'call-with-input-file', 'call-with-output-file',
'with-input-from-file', 'with-output-to-file', and
'with-error-to-file', that accept keyword arguments '#:binary',
'#:encoding', and (for input port constructors) '#:guess-encoding'.
* doc/ref/api-io.texi (File Ports): Update documentation.
* test-suite/tests/ports.test ("keyword arguments for file openers"):
Add tests.
* libguile/finalizers.c: New excitement! We'll be running finalizers
asynchronously, from asyncs. This will make it safer to allocate
while holding a mutex.
(GC_set_finalizer_notifier): Add back-compat shim.
* libguile/init.c (scm_i_init_guile): Init the async finalizer mechanism
during boot.
* libguile/gc.c (scm_storage_prehistory): Tell libgc we'll be finalizing
on demand.
(scm_gc): Explicitly run finalizers here.
* libguile/threads.c (guilify_self_2): Run finalizers here if
queue_finalizer_async happened to run during guilify_self_1.
* configure.ac: Add check for GC_set_finalizer_notifier.
* libguile/finalizers.c: New excitement! We'll be running finalizers in
threads, if that's available. If it's not available, during early
boot, we can run finalizers in asyncs. This will make it safer to
allocate while holding a mutex.
* libguile/posix.c (scm_fork): Shut down the finalizer thread before
forking.
* libguile/init.c (scm_i_init_guile): Init the async finalizer mechanism
during boot and, if available, initialialize the finalizer thread at
the very end.
* libguile/gc.c (scm_storage_prehistory): Tell libgc we'll be finalizing
on demand.
(scm_gc): Explicitly run finalizers here. If you're calling this
function, you probably want synchronous GC.
* libguile/fports.c (scm_revealed_count, scm_port_revealed)
(scm_set_port_revealed_x, scm_adjust_port_revealed_x): Move these APIs
here, and only operate on fports. To keep revealed ports alive, now
we will just keep them in a data structure that the GC knows about --
a static list.
* libguile/fports.h: Add revealed count to scm_t_fport, and move decls
of revealed-count functions here.
* libguile/ports.h:
* libguile/ports.c: Adapt to change. Remove SCM_REVEALED and
SCM_SETREVEALED; since they only apply to fports now, keeping them
around would be inviting type errors.
(finalize_port): We don't need to worry about resuscitating ports
here.
* libguile/init.c: Use the scm_set_port_revealed_x function to set the
revealed counts on stream ports.
* libguile/weak-set.c (make_weak_set):
* libguile/weak-table.c (make_weak_table): If we have a threaded Guile,
* keep a weak set (table) of weak sets (tables). Use this and the
pthread_atfork mechanism to lock and unlock weak sets and weak tables
during a fork().
* libguile/weak-set.h (scm_weak_set_prehistory): New internal API.
* libguile/init.c: Add call to scm_weak_set_prehistory().
This should help with regex portability, as reported in
<http://bugs.gnu.org/10684> for Darwin 8.11.
* m4/gnulib-cache.m4 (gl_MODULES): Add `regex'.
* configure.ac: Remove header checks for regex.h, rxposix.h, and
rx/rxposix.h. Remove check for the `regcomp' function. Remove
definition of `HAVE_REGCOMP'. Define `ENABLE_REGEX'.
* libguile/init.c: Check for `ENABLE_REGEX' instead of `HAVE_REGCOMP'.
* libguile/regex-posix.c: Always include <regex.h>. Remove #ifdefs for
rxposix.h and co.
This is a temporary workaround for the 2.0 stable series. The next
stable series should have an implicit `setlocale (LC_ALL, "")' call,
which will make this unnecessary.
* libguile/feature.c (progargs_fluid): Rename to...
(scm_program_arguments_fluid): ... this. Update users.
* libguile/feature.h (scm_program_arguments_fluid): New internal
declaration.
* libguile/init.c (invoke_main_func): Call
`scm_i_set_boot_program_arguments' instead of
`scm_set_program_arguments'.
* libguile/script.c (locale_arguments_to_string_list,
scm_i_set_boot_program_arguments): New functions.
(scm_compile_shell_switches): Use `locale_arguments_to_string_list'.
* libguile/script.h (scm_i_set_boot_program_arguments): New internal
declaration.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add
`test-command-line-encoding'.
* test-suite/standalone/test-command-line-encoding: New file.
* libguile/weak-vector.c:
* libguile/weak-vector.h: Renamed from weaks.[ch]. Remove weak pairs.
They were not safe to access with `car' and `cdr'. Remove weak alist
vectors, as we have weak tables and sets. Reimplement weak vectors,
moving the implementation here.
* libguile/vectors.c:
* libguile/vectors.h: Remove the extra header word. Use
scm_c_weak_vector_ref / scm_c_weak_vector_set_x to access weak
vectors.
* libguile/snarf.h: Remove the extra header word in vectors.
* libguile/threads.c (do_thread_exit, fat_mutex_lock, fat_mutex_unlock):
Instead of weak pairs, store thread-owned mutexes in a list of
one-element weak vectors.
* libguile/guardians.c (finalize_guarded): Similarly, store object
guardians in a list of one-element weak vectors.
* libguile/modules.c (scm_module_reverse_lookup): We no longer need to
handle the case of weak references.
* libguile/print.c (iprin1): Use the standard vector accessor to print
vectors.
* libguile.h:
* libguile/Makefile.am:
* libguile/gc-malloc.c:
* libguile/gc.c:
* libguile/goops.c:
* libguile/init.c:
* libguile/objprop.c:
* libguile/struct.c: Update includes.
* module/ice-9/weak-vector.scm: Load weak vector definitions using an
extension instead of %init-weaks-builtins.
* test-suite/tests/weaks.test: Use the make-...-hash-table names instead
of the old alist vector names.
* libguile/weak-table.c:
* libguile/weak-table.h: New files, implementing open-addressed weak
hash tables, similar to the implementation of weak sets. This will
let us remove weak pairs.
* libguile.h:
* libguile/Makefile.am:
* libguile/evalext.c:
* libguile/gc.c:
* libguile/init.c:
* libguile/print.c:
* libguile/tags.h: Update all the pieces for the new files and tc7.
* libguile/weak-set.c:
* libguile/weak-set.h: New files, implementing weak sets, for use in the
symbol table and port set. Eventually we will be able to remove weak
pairs.
* libguile.h:
* libguile/Makefile.am: Add new files.
* libguile/evalext.c:
* libguile/gc.c:
* libguile/init.c:
* libguile/print.c:
* libguile/tags.h: Add support for the new types.
* libguile/init.h:
* libguile/init.c (scm_i_init_guile): Change arg to this internal
function from SCM_STACKITEM* to void*. Actually it's a
struct GC_stack_base*.
* libguile/bdw-gc.h: Don't do pthread redirects, because we don't want
to affect applications' pthread_* bindings.
* libguile/pthread-threads.h (scm_i_pthread_create)
(scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel)
(scm_i_pthread_sigmask): Do pthread redirects here, in this internal
header.
* libguile/threads.h: Remove declaration of internal
scm_i_with_guile_and_parent. Remove declaration of undefined
scm_threads_init_first_thread. Make declaration of internal
scm_threads_prehistory actually internal, and take a void* (actually a
struct GC_stack_base*).
* libguile/threads.c (GC_get_stack_base): Implement a shim if this
function is unavailable, and fold in the implementations of
get_thread_stack_base.
(GC_call_with_stack_base): Actually implement.
(guilify_self_1): Take a GC_stack_base* as an arg.
(scm_i_init_thread_for_guile): Likewise, and set up libgc for
registration of other threads.
(scm_init_guile): Use GC_get_stack_base instead of our own guesswork.
(with_guile_and_parent, scm_i_with_guile_and_parent): Rework to
trampoline through a GC_call_with_stack_base.
(scm_threads_prehistory): Pass the "base" arg on to guilify_self_1.
* 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.
