* module/srfi/srfi-19.scm (encode-julian-day-number)
(decode-julian-day-number, date-week-number): Use 'floor-quotient'
instead of 'quotient', and 'floor' instead of 'truncate', where
appropriate.
(time-utc->date): Ensure that the 'nanoseconds' field of the returned
date is non-negative.
(leap-year): Handle negative years properly, and reformulate the
computation.
(week-day): Handle negative years properly. Use 'floor-quotient'
instead of 'quotient' where appropriate.
(directives): In the handler for '~Y' format escapes, improve the
handling of years outside of the range 0-9999.
(read-directives): Add a FIXME comment to fix the '~Y' reader to handle
years outside of the range 0-9999.

of Julian Day and Modified Julian Day. Give the correct full names of
UTC and TAI.
* module/srfi/srfi-19.scm: Import (srfi srfi-1). Use modern Guile
keyword syntax in the 'define-module' form.
(leap-second-neg-delta): New procedure, derived from a similar procedure
in the latest upstream SRFI-19 reference implementation.
(priv:time-tai->time-utc!, time-tai->julian-day)
(time-monotonic->julian-day): Use 'leap-second-neg-delta'.

leap second handling, following upstream SRFI-19.

(date->time-tai, date->time-monotonic): Add special leap second
handling, following upstream SRFI-19.

Fixes <https://bugs.gnu.org/33036>.
Reported by <calcium@disroot.org>.
* module/language/cps/types.scm (define-simple-type-inferrer):
Apply (logand (&type val) <>) uniformly. Previously, this was done only
in the false branch. Rename local variable to 'type*', to allow the
macro operand 'type' to be an arbitrary expression.

* libguile/numbers.c: Add another top-level 'verify' to ensure that
LONG_MIN is not a fixnum.
(scm_ash, scm_round_ash): Ensure that when the shift count is LONG_MIN,
it is not handled via the normal code path, to avoid signed overflow
when the shift count is negated.
* test-suite/tests/numbers.test: Add tests.
This is a followup to commit 011aec7e24.
When rounding, right shifting a negative integer by a huge shift count
results in 0, not -1.
* libguile/numbers.c: Add top-level 'verify' to ensure that the
assumptions in 'scm_ash' and 'scm_round_ash' are valid.
(scm_round_ash): In the case that handles huge right shifts, require
that the shift count _exceeds_ the integer length, and return 0 instead
of -1.
* test-suite/tests/numbers.test: Adjust tests accordingly.
Fixes <https://bugs.gnu.org/32644>.
Reported by Stefan Israelsson Tampe <stefan.itampe@gmail.com>.
The need for this arose because the type inferrer for 'ursh' sometimes
passes (- 1 (expt 2 64)) as the second argument to 'ash'.
* libguile/numbers.c (scm_ash, scm_round_ash): Gracefully handle several
cases where the shift count does not fit in a C 'long'.
* test-suite/tests/numbers.test: Add tests.

("recursive lock waits")
("mutex unlock is false when condition times out"): Adjust cases where
