To address the usual portability/correctness issues (new and improved
with C2x looming :-) I merged from current Gnulib into the emacs-28
branch, and this merge should eventually hit the Emacs master branch. As
it's been a while since the last merge from Gnulib I expect there will
be some glitches; please let me know what you run into. You will
probably need to build from scratch or do a 'make bootstrap'.
One thing in particular: 'configure' now prefers 64-bit to 32-bit time_t
on platforms that have both. The only known platforms like this are
glibc 2.34+ on ARM and x86. The upside is that Emacs won't stop working
after 2038 on these 32-bit platforms; the downside is that there may be
issues (which we don't yet know about) if Emacs is linked to libraries
that require time_t to be 32 bits. If you encounter the downsides you
can configure with --disable-year2038. Please let me know of any
problems in this area; I have tested this on Fedora 34 x86 client, but
not on other platforms.
There's a bit more discussion about this merge here:
