This is the same strategy as used for the 'accept4' bindings introduced
in 6e0965104c.
* libguile/posix.c (scm_pipe): Rename to...
(scm_pipe2): ... this. Add an optional 'flags' parameter and honor it.
(scm_pipe): Rewrite as a call to 'scm_pipe2'.
* libguile/posix.h (scm_pipe2): New declaration.
* test-suite/tests/posix.test ("pipe"): New tests.

* NEWS: Update.
The underlying function was moved to filesys.c in
073167ef7b but the declaration didn't follow
* libguile/filesys.h: add declaration for scm_mkstemp
* libguile/posix.h: remove declaration for scm_mkstemp
As the FSF advises, 'There is no legal significance to using the
three-character sequence “(C)”, but it does no harm.' It does take up
space though! For that reason, we remove it here from our C files.
* libguile/simpos.c: Trim includes.
(scm_system_star): Move to posix.c.
* libguile/simpos.h (scm_system_star): Remove.
* libguile/posix.h (scm_system_star): Add.
* libguile/posix.c (scm_system_star): Move here and implement in terms
of open-process. This lets system* work on Windows. Inspired by a
patch by Eli Zaretskii.
(start_child): Exit with 127 if the command isn't found.
* libguile/posix.c (scm_total_processor_count,
scm_current_processor_count): New functions.

returns 8 bytes of a user's login.
* doc/ref/posix.texi: Remove cuserid from docs.
* 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.
* configure.ac: Check availability of getsid() C library call.
* libguile/posix.c (scm_getsid): New primitive.
* libguile/posix.h: Declaration for new primitive.
Ports are given two additional properties: a character encoding and
a conversion failure strategy. These properties have getters and setters.
The new properties are used to convert any locale text to/from the
internal representation of strings.
If unspecified, ports use a default value. The default value of these
properties is held in a fluid. The default character encoding can be
modified by calling setlocale.
ISO-8859-1 is treated specially. Since it is a native encoding of
strings, it can be processed more quickly. Source code is assumed to be
ISO-8859-1 unless otherwise specified. The encoding of a source code
file can be given as 'coding: XXXXX' in a magic comment at the top of a
file.
The C functions that deal with encoding often use a null pointer
as shorthand for the native Latin-1 encoding, for efficiency's sake.

functions scm_getc, scm_unget_byte, scm_ungetc,
scm_i_get_port_encoding, scm_i_set_port_encoding_x,
scm_port_encoding, scm_set_port_encoding_x,
scm_i_get_conversion_strategy, scm_i_set_conversion_strategy_x,
scm_port_conversion_strategy, scm_set_port_conversion_strategy_x.
* libguile/ports.c: assign the current ports to zero on startup so
we can see if they've been set.
(scm_current_input_port, scm_current_output_port,
scm_current_error_port): return #f if the port is not yet
initialized
(scm_new_port_table_entry): set up a new port's encoding and
illegal sequence handler based on the thread's current defaults
(scm_i_remove_port): free port encoding name when port is removed
(scm_i_mode_bits_n): now takes a scheme string instead of a c
string and length. All callers changed.
(SCM_MBCHAR_BUF_SIZE): new const
(scm_getc): new function, since the scm_getc in inline.h is now
scm_get_byte_or_eof. This pulls one codepoint from a port.

(scm_unget_byte): new function, incorportaing the low-level functionality
of scm_ungetc
(scm_ungetc): uses scm_unget_byte

with declaration of scm_t_wchar
* README: Some rewording.
* configure.in: Check for getrlimit and setrlimit.
* libguile/posix.h:
* libguile/posix.c: Add some getrlimit and setrlimit wrappers. They're
documented, but I suspect something else has to be done to get them
into the manual.
NULL. rewrote the docstring.
(scm_mkstemp): new procedure implementing "mkstemp!".
* posix.h: declare scm_mkstemp.
* net_db.c: declare h_errno if configure didn't define HAVE_H_ERRNO.
normally it would be found in netdb.h.
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
* stime.c (scm_times): new procedure.
* ioext.c (scm_fseek): if the first argument is a file descriptor
call lseek.
(scm_ftell): if the first argument is a file descriptor call lseek
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.
(scm_truncate_file): new procedure.
Add DEFER/ALLOW INTS to a few other procedures.
(scm_fsync): new procedure.
(scm_open_fdes): new procedure.
(scm_open): use scm_open_fdes. If mode isn't specified, 666 will
now be used.
(scm_fcntl): the first argument can now be a file descriptor. The
third argument is now optional.
* posix.c (scm_execl, scm_execlp): make the filename argument
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c. disable interrupts.
(scm_convert_exec_args): take pos and subr arguments and
improve error checking.
* boot-9.scm: define tms accessors: clock, utime, stime, cutime,
cstime.
* Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
* configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
* putenv.c: new file, from sh-utils 1.12.
* posix.c (scm_environ): use malloc in place of scm_must_malloc
since allocation isn't for Scheme objects.
(scm_putenv): copy strings before placing in the environment.
* stime.c (scm_current_time): throw an error if time returns -1,
instead of returning #f.
(scm_get_internal_real_time, scm_get_internal_real_time): use
scm_long2num for return value instead of SCM_MAKINUM.

* stime.c (scm_time_in_msec): apparently unused, deleted.
* configure.in: check for gettimeofday.
* stime.c (scm_time_plus_ticks): new procedure, an scsh interface
which may be more usefully portable than a gettimeofday interface.
* stime.c (filltime): recovered static procedure.
(scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
an earlier Guile.
* posix.h: add prototype for scm_close_pipe, remove prototypes for
scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
* * posix.c (scm_mknod): split the mode argument into type and perms
arguments, like the extra fields returned by stat.
* fports.c (scm_pipob): set the close, free and print procedures.
(scm_close_pipe): new procedure.
* posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
define them in boot-9.scm
wan't defined. Don't include fd.h.
* Previously fd.h was regenerated whenever configure was run,
forcing a couple of files to be recompiled.
* fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
* configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
Check for _fileno as well as _file.
Don't output fd.h.
* ioext.c: don't fd.h.
* acconfig.h: remove duplicate HAVE_FD_SETTER and change the
other to FD_SETTER.
* Change the stratigy for getting information about errno
(and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
generating lists of symbols during the build process, which will
not always work, include comprehensive lists in the distribution.
To help keep the lists up to date, the "check_signals" and
"check_errnos" make targets can be used.
* configure.in: don't check for a command to extract errno codes.
* Makefile.am: update file lists, remove errnos.list and errnos.c
targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
check_errnos targets.
(CLEANFILES): remove errnos.c and errnos.list, add
cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
* errnos.default: deleted.
* cpp_signal.c: new file.

* cpp_err_symbols, cpp_sig_symbols: new files.
* cpp_cnvt.awk: renamed from errnos_cnvt_awk.
* error.c (scm_init_error): #include cpp_err_symbols instead of
errnos.c.
* posix.c (scm_init_posix): don't intern signal symbols. #include
cpp_sig_symbols.c.
* strop.c (scm_i_index): allow the lower bound to be equal to the
length of the string, so a null string doesn't always give an error.
* posix.h: new prototypes.
* posix.c (scm_status_exit_val, scm_status_term_sig,
scm_status_stop_sig): new functions, as in scsh. They break down
process status values as returned by waitpid.
* Makefile.am: remove AWK=@AWK@.
Add a rule for generating errnos.list.
(CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
* configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
don't extract errnos, just set a variable (avoids the
need to recompile error.c just because configure is run.)
* unif.h: update prototypes.
* unif.c (scm_uniform_array_read,write): change the offset and
length arguments to start and end, for consistency.
* __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
* ioext.h: update prototypes.
* * ioext.c (scm_read_delimited_x): replaces scm_read_line and
scm_read_line_x, it's a more general procedure using an
interface from scsh. read-line and read-line! are now defined
in boot-9.scm.
* Note that the new read-line trims the terminator
by default, previously it was appended to the returned string. An
optional argument specifies how to process the terminator (scsh
compatible). For the old behaviour: (read-line port 'concat).
scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
returns a pair, but is converted to multiple values if the scsh
module is loaded.
socket.h: update prototypes.
* socket.c (scm_recvfrom): for consistency with other procedures,
take start and end as separate optional arguments.
* (scm_recv, scm_recvfrom): don't allow the second argument
to be a size, only a buffer. Change the scheme names to
recv! and recvfrom!. Don't return the buffer.
* ioext.h, posix.h: move prototypes too.
* ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
moved back from posix.c to ioext.c. Also move #includes of "genio.h"
"read.h" and "unif.h".
* ioext.c: include "chars.h"
is available in a FILE structure, which is needed by char-ready.
* acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
FILE_CNT_READPTR.
* simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
exceptions using misc_error instead of syserror. It seems a bit
odd to throw an exception if a string can't be found in the
environment, but it's consistent with open-file, stat etc.
(simpos.h): remove sys_ from getenv.
* posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
occurs, throw an error instead of returning errno. Return value
is now unspecified.
(numerous in posix.c and posix.h): removed superfluous sys_ from names.
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.
