The current recommendation of `list-copy' is not right and does not lead
to preserving the original list:
scheme@(guile-user)> (define x (list (cons 'a 1) (cons 'b 2)))
scheme@(guile-user)> (define y (list-copy x))
scheme@(guile-user)> (assq-set! y 'b 3)
$1 = ((a . 1) (b . 3))
scheme@(guile-user)> x
$2 = ((a . 1) (b . 3))
Correct approach seems to be use `alist-copy' from SRFI-1 leading to the
expected behavior of:
scheme@(guile-user)> ,use (srfi srfi-1)
scheme@(guile-user)> (define x (list (cons 'a 1) (cons 'b 2)))
scheme@(guile-user)> (define y (alist-copy x))
scheme@(guile-user)> (assq-set! y 'b 3)
$1 = ((a . 1) (b . 3))
scheme@(guile-user)> x
$2 = ((a . 1) (b . 2))

If pipe2 is not available (e.g. on MacOS) and flags are set,
SCM_SYSERROR was correctly signaled, however errno was not set, so it
reported as:
Undefined error: 0
That sucks both in tests (the test is not skipped) and in actual
usage (user has no idea what went wrong).
So set errno to ENOSYS as well.

Darwin accepts any template, as demonstrated here:
#include <stdio.h>
#include <unistd.h>
int
main(void)

char *res = mkdtemp(template);
puts(res ? res : "(null)");
perror("mkdtemp");
}
Outputs:

When passed a port, `readlink' relies on the Linux specific behavior of
empty c_path meaning "the fd itself". That does not work on Darwin.
Since there is no branch that would yield both fd and c_path, fallback
to freadlink when __APPLE__ is defined.

Hole are itself a file-system specific feature and they are not
mandated. While APFS does support sparse files, they do not behave like
on Linux. I did not discover exact rules, but the file needs to be
large (100s of kB at least) and the holes are not aligned as the test
code expects. So just disable them.

POSIX does not explicitly say that stored value using setsockopt will be
returned by getsockopt. At least for TCP_NODELAY on Darwin they do
differ. Darwin returns internal define TF_NODELAY (4) instead of 1 the
test expected. Since for boolean flags "non-zero is true", rewrite the
test to check just that.

* libguile/Makefile.am: add new header file setjump-win.h
* libguile/continuations.h, libguile/dynstack.c, libguile/dynstack.h,
libguile/intrinsics.h, libguile/vm.h:
supply custom `setjmp` macro on Windows
Mingw implements `setjmp (env)` as a macro that expands to
_setjmp (env, faddr)
where `faddr` is set to the current frame address.
This address is then stored as first element in the jump buffer `env`.
When `longjmp` is called, it tries to unwind the stack up
to the saved address by calling `RtlUnwindEx` from MSVCRT,
which will fail, if the stack frames are interwoven with
JIT-generated code, that violate the Windows x64 calling conventions.
Thus implement the macro ourselves as
_setjmp (env, NULL)
which will toggle a code path in `longjmp` that does no unwinding.

* configure.ac: when -fexcess-precision=standard is available and we're
building for i[3456]86, use it. This fixes floating point precision
problems caused by x87 (80-bit) floating point, and detected by
numbers.test.
Closes: 43262
The tests depend on libguile/guile-procedures.txt, for example via
documented? in bit-operations.test. Previously "make check -j..." in a
clean tree would fail because libguile/guile-procedures.txt is built by
./Makefile.am (rather than libguile/Makefile.am) so that it will have a
built module/ available, but when "." is not listed in SUBDIRS, it
builds last, and so the test-suite runs before guile-procedures.txt is
built.
To fix the problem add "." to SUBDIRS before the test-suite so that the
tests will be able depend on everything else, and move the existing
guile-procedures.txt target into libguile/ next to its
guile-procedures.texi dependency. That gives a better overview and
simplifies the recipe a bit. It also allows us to drop the explict
"all-local:" dependency, and to let the existing libguile/ code handle
the cleanup.
* Makefile.am (SUBDIRS): add . just before the test-suite.
(libguile/guile-procedures.txt): rely on libguile/Makefile.am.
(CLEANFILES): Drop libguile/procedures.txt.
* libguile/Makefile.am: (all-local): drop.
(libguile/guile-procedures.txt): move Makefile.am recipe here.
