Custom ports are a kind of port that exposes the C port type interface
directly to Scheme. In this way the full capability of C is available
to Scheme, and also the read and write functions can be tail-called from
Scheme (via port-read / port-write).
* libguile/custom-ports.c:
* libguile/custom-ports.h:
* module/ice-9/custom-ports.scm: New files.
* libguile/init.c:
* libguile/Makefile.am:
* am/bootstrap.am: Add to the build.
* doc/ref/api-io.texi: Update the manual.
* doc/ref/api-binding.texi (Local Bindings): Document multiple-value
returns for let.
* doc/ref/api-control.texi (begin): Document multiple-value returns for
begin.
(Conditionals): Document multiple-value returns and use 'body' in the
syntax description of when, unless, cond, case.
(Multiple values): Document multiple-value returns and use 'body' in
the syntax description of SRFI-8 receive.
(Fluids and Dynamic States): Use 'body' in the syntax description of
'with-fluids'.
This commit adds internal definitions to the following derived
forms: when, unless, cond, case, with-fluids, and and-let*.
* doc/ref/api-control.texi (Conditionals): Update the syntax and docs
of when, unless, cond, and case.
* module/ice-9/and-let-star.scm (and-let*): Changed begins to let.
* module/ice-9/boot-9.scm (cond, case, when, unless, with-fluids):
Changed begins to let.
This is a followup to edfca3b7e5, which
added the 'posix_spawnp' module but not 'posix_spawn'.
* m4/gnulib-cache.m4: Add 'posix_spawn' module.
* gnulib-local/m4/clock_time.m4.diff: Adjust.
* configure.ac: Move 'gl_EARLY' use right after 'AC_PROG_CC'.
* doc/ref/api-macros.texi: make the macro expand to the literal
date, not to a call to the date function. The example previously
did not actually need eval-when and did not show the intended
effect.
* module/rnrs/bytevectors/gnu.scm: New file.
* am/bootstrap.am (SOURCES): Add it.
* libguile/bytevectors.c (scm_bytevector_slice): New function.
* libguile/bytevectors.h (scm_bytevector_slice): New declaration.
* test-suite/tests/bytevectors.test ("bytevector-slice"): New tests.
* doc/ref/api-data.texi (Bytevector Slices): New node.

The spelling mistake is a clear fix, but the Arrays fix might not be as
obvious. Previously, with the "arrays" alias, the @ref macro would
render a superfluous period after the word "arrays", rendering (at least
within Emacs) as:
you may wish to use see arrays. instead.
