The idea behind those functions is not to force consumers to remember that there
is a need to check errno on failure. We already have a caph_enter(3) function
which does the same for cap_enter(2).

The comment isn't stale. The check is bogus in the sense that poll(2)
does not require pollfd entries to be unique in fd space, so there is no
reason there cannot be more pollfd entries than open or even allowed
fds. The check is mostly a seatbelt against accidental misuse or
abuse. FD_SETSIZE, while usually unrelated to poll, is used as an
arbitrary floor for systems with very low kern.maxfilesperproc.
Additionally, document this possible EINVAL condition in the poll.2
manual.
No functional change.

Enabling BSD_CRTBEGIN on amd64 resulted in
error: unused variable '__CTOR_LIST__'.
__CTOR_LIST__ is indeed unused in crtbegin.c; it marks the beginning of
the .ctors array and is used in crtend.c. Annotate __DTOR_LIST__ as

If RLIM_INFINITY == -1ULL (such as on macOS) the min() call will result
in a value of less than 1 being returned. This causes nftw() to fail
with EINVAL.
While touching this file also fix includes to work on Linux/macOS and don't
declare snprintf since it may have different attributes in the system
headers there.

timezone offset. These values are generally zero.
While one still theoreticall could set these values, that's almost
never done. Users wishing to have an offset between the time of day
clock hardware and UTC use adjkerntz(8) instead.
localtime(3) should be used to find these values for the current
timezone.
Flags prevent open(2) and *at(2) vfs syscalls name lookup from
escaping the starting directory. Supposedly the interface is similar
to the same proposed Linux flags.

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.
This is currently disabled until __dso_handle support is added.

The script uses shift three times and when building with a strict /bin/sh
shifting without any arguments will cause the script to fail. In this case
the target will fail and we write an empty output file. When doing a
NO_CLEAN build after this will mean fallback.c is up to date and clang
will happily compile the empty input file which leads to strange build
errors later.
Fixed by passing three empty arguments to MkFallback.sh and only creating
fallback.c if MKfallback.sh succeeds.

There was an additional + after the {6} which is apparently ignored by the
FreeBSD regex implementation but was giving me an error when compiling on
MacOS.
While changing this also make sure that tables.h is not created if mktables
fails. The current rule would create a partial tables.h which causes following
incremental builds to use that broken file and fail with an unrelated
compilation error or even succeed even though they shouldn't.
