These are important for reliable networking, since they prevent network
operations from hanging indefinitely.

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'.

* test-suite/tests/posix.test ("pipe"): New tests.
* configure.ac: Look for 'pipe2'.

This port is of limited use if it cannot be used reliably. Rather than

raise an exception.

* libguile/deprecated.c (make_bignum): Move here from numbers.c, to
support scm_i_long2big etc.
(scm_i_big2dbl):
(scm_i_long2big):
(scm_i_ulong2big):
(scm_i_clonebig):
(scm_i_normbig): Deprecate.
(scm_install_gmp_memory_functions): Deprecate, happily! SCM bignums now
have digits allocated inline with the bignum itself, so they are
completely transparent to the GC already. The price is that if GMP ever
allocates digits via the MPZ API, those digits then have to be copied
back into managed memory. But we avoid having to install finalizers and
we avoid having to muck with GMP's allocator.
* libguile/numbers.c (scm_from_mpz): Use scm_integer_from_mpz.
(scm_init_numbers): Never muck with GMP's allocators.
* doc/ref/guile-invoke.texi (Environment Variables): Remove note about
GUILE_INSTALL_GMP_MEMORY_FUNCTIONS.
* meta/build-env.in: No need to set GUILE_INSTALL_GMP_MEMORY_FUNCTIONS.
This patch removes the undocumented function make-srfi-4-vector from
(guile). That function is still exported from (srfi srfi-4 gnu).
* libguile/srfi-4.h (scm_init_srfi_4): Split into scm_bootstrap_srfi_4()
and scm_init_srfi_4(), after the pattern of scm_init_bytevectors() and
scm_bootstrap_bytevectors().
* libguile/init.c: Replace scm_init_srfi_4() call by scm_bootstrap_srfi_4().
* module/srfi/srfi-4.scm: Load newly defined srfi-4 extension. This
provides undocumented make-srfi-4-vector.
* module/srfi/srfi-4/gnu.scm: Export srfi-4-vector-type-size.
* doc/ref/srfi-modules.texi: Document srfi-4-vector-type-size.

SCM_FOREIGN_TYPE_COMPLEX_DOUBLE): New enums.
* module/system/foreign.scm (complex-float, complex-double): Export new types.
(make-c-struct, parse-c-struct): Support the new types.
* libguile/foreign.c (complex-float, complex-double): Define new types.
(alignof, sizeof, pack, unpack): Support the new types.
* test-suite/tests/foreign.test: Test.
These use the argument conventions of vector-copy!, string-copy!,
etc. and not that of bytevector-copy! (which is from r6rs).
* module/srfi/srfi-4/gnu.scm: As stated.
* test-suite/tests/srfi-4.test: Tests.
* doc/ref/srfi-modules.texi: Documentation.
* libguile/bytevectors.c (bytevector-copy!): Add overlap note to
docstring.
* libguile/vectors.c (vector-copy!): Reuse text for the overlap note.

(scm_bytevector_fill_x): Stub to avoid changing the C API.
* doc/ref/api-data.texi: Documentation.
* libguile/vectors.c (vector-fill!): Less confusing variable names.
* test-suite/tests/bytevectors.test: Test partial fill cases for
bytevector-fill!.
* Deprecate scm_is_simple_vector.
* libguile/vectors.c (scm_vector_elements,
scm_vector_writable_elements): These functions take an array; reword
to make this clear.
* libguile/print.h: Remove reference to 'simple vector'.
* doc/ref/api-data.texi: Remove documentation for scm_is_simple_vector.
Remove references to 'simple vector'.
Fix documentation for scm_vector_elements,
scm_vector_writable_elements.
* test-suite/tests/arrays.test:
* test-suite/tests/vectors.test: Remove references to 'simple vector'.
This is up to 20%-30% faster than the previous versions in (scheme base) or
(srfi srfi-43) that used vector-move-left!/vector-move-right!.
* libguile/vectors.h:
* libguile/vectors.c: As stated.
* doc/ref/api-data.texi (vector-copy!): Document the new function.
(vector-fill!): Document optional arguments.
(vector-copy): Document optional arguments.
* module/scheme/base.scm: Reuse core vector-copy!.
* module/srfi/srfi-43.scm: Reuse core vector-copy!.
In the part about lambda formals, change "arguments will converted into"
to "arguments will BE converted into".
* doc/ref/api-procedures.texi (Lambda: Basic Procedure Creation):
Fix typo.
When using automake and libtool to build DLLs on Cygwin, libtool
will rename libXXX to cygXXX. 'load-foreign-library' should
emulate libltdl behavior and search for DLLs using that convention.
* module/system/foreign-library.scm (lib->cyg): new helper function
(load-foreign-library): add rename-on-cygwin? option to rename
libraries using Cygwin semantics
* test-suite/tests/foreign.test: new test section 'lib->cyg'
* doc/ref/api-foreign.text: document new rename-on-cygwin? option
for load-foreign-library
This reverts commit 0f983e3db0.
After discussing with Mike we are going to punt the read-line changes
for now. Open the port in O_TEXT mode if you want to chomp the CR in
CFLF sequences.
* libguile/rdelim.c (scm_read_line): handle CRLF, LS and PS
* module/ice-9/suspendable-ports.scm (read-line): handle CRLF, LS, and PS
* module/web/http.scm (read-header-line): take advantage of CRLF in read-line
(read-header): don't need to test for \return
* test-suite/tests/rdelim.test: new tests for read-line CRLF, LS and PS
* doc/ref/api-io.texi: update doc for read-line
* doc/ref/posix.texi (File System): Update to document mkstemp only.
* libguile/filesys.c: Make a mkstemp that doesn't modify the input
template. Instead the caller has to get the file name from
port-filename.
(scm_mkstemp): Use the new mkstemp to implement mkstemp!. Can't
deprecate yet though as the replacement hasn't been there for long
enough.
* libguile/posix.c (scm_tempnam): Update to mention mkstemp instead.
* module/system/base/compile.scm (call-with-output-file/atomic): Use
mkstemp.
* test-suite/tests/posix.test:
* test-suite/tests/r6rs-files.test: Use mkstemp.
* NEWS: Update.
