[bug #65537] Werrors from intprops-internal.h with gcc 8.3.0

[Martin Dorey]

Follow-up Comment #4, bug #65537 (group make):

I made that change, then, not knowing how to activate it, just tried running
bootstrap again.  That failed the same way I saw, but didn't report, earlier
today, somehow clobbering the gnulib that had been cloned before, causing a
second run of bootstrap to clone the desired version:

martind@stormy:~/download/make-2024-03-29$ ./bootstrap 
./bootstrap: Bootstrapping from checked-out make sources...
error: pathspec 'stable-202401' did not match any file(s) known to git
martind@stormy:~/download/make-2024-03-29$ ./bootstrap 
./bootstrap: Bootstrapping from checked-out make sources...
./bootstrap: getting gnulib files...

As might be expected from the previously queried change for disabling the
type-limits warning for gcc >= 5, a threshold that seems somewhat unlikely to
have been deliberate, I'm left with just the sign-compare one:

mv -f $depbase.Tpo $depbase.Po
