Triggered by 'sizeof(int())'.
GCC evaluates this expression to 1, without any warning.
Clang warns about an "invalid application of 'sizeof' to a function
type".
When sorting the words of an expression numerically using the modifier
':On' (added on 2021-07-30), use 64-bit numbers even on 32-bit
platforms. A typical use case is comparing file sizes.
When tracing the execution of jobs, fix an integer overflow after 2038.
32-bit platforms that use a pre-C99 compiler still have this problem.
No change to the test suite since most tests simply skip any potential
differences between 32-bit platforms and 64-bit platforms (see
varmod-order-numeric.mk) or already account for both variants (see
varmod-localtime.mk).
Since .POSIX: is required to be the first non-comment line
in a Makefile, including ${MAKE_POSIX_MK} or whatever _PATH_POSIX_MK is
set to at this point is equivalent to an extension of sys.mk
This is a minimal change that can allow a better approximation of
POSIX compliance

Only print the heading for the symbol table level if there is actually a
symbol on that level.
Ensure that no symbol with block level -1 is ever in the symbol table

Refactoring work in man.c r. 1.40 from twelve years ago introduced a
regression where input from the -m option was appended rather than
prepended to the search paths. Problem reported by C. Chapman on
netbsd-users.
The unit-tests for meta mode do not depend on filemon.
Adding nofilemon to .MAKE.MODE allows these to pass on
a system that would use filemon_dev but does not have
the module loaded.
Previously, the string literals "1" "2" "3" "4" were concatenated in the
order "23", "234", "1234". This influenced the location of the
diagnostics for traditional C (which doesn't know concatenation at all)
and for mixing regular strings and wide strings.
Now the diagnostics occur exactly where they are expected. The first
string literal defines whether the whole string is regular or wide, and
any further string literals must match it.
In traditional C mode, there are more diagnostics than before, but that
doesn't hurt since they are still correct and nobody uses lint in
traditional C mode anyway.
There is no need to make this variable externally visible. There are
several more variables in this file that could be unexported, leave
these for someone who knows whether vmstat.c is used by other parts of
the tree as well.
No functional change, OK mrg.
No functional change. As before, the string literals "1" "2" "3" are
not concatenated from left to right, instead concatenation starts with
"23" and then proceeds to "123".
