Discussion of these changes can be found on the Mercury developers
mailing list archives from June 2018.
COPYING.LIB:
Add a special linking exception to the LGPL.
*:
Update references to COPYING.LIB.
Clean up some minor errors that have accumulated in copyright
messages.
library/time.m:
Deprecate non-pure functions `localtime/1' and `mktime/1'.
They depend on the current time zone, which depends on the
environment that the program is running in, and may also be
changed at run time (e.g. by setting the environment variable
"TZ").
Add replacement predicates `localtime/4' and `mktime/4' that
thread the I/O state.
Deprecate the non-pure function `ctime/1'. It does not seem
necessary to add a pure replacement for it, being a minor
convenience at best.
Try to clarify some documentation.
