The function is obsolete. It is recommended to use getrlimit(2) instead
(see the manual page for ulimit(3) or the POSIX manual for it). Since
getrlimit(2) is required by POSIX.1-2001, we can rely on it.

ISO C99 requires <locale.h>.
Other files in the project already include <locale.h> unconditionally,
so it's reasonable to assume that it is always available.

The missing #include <gshadow.h> causes the configure check to fail
spuriously, resulting in HAVE_SHADOWGRP not being defined even
on systems that actually have sgetsgent (such as current glibc).
Version 1.19.1 was released in June 2014.

This used to be 16 for historical reasons but these days basically every
distro configures --with-group-name-max-length=32 to make it match the
max Linux username length, make it default.

C89 and POSIX.1-2001 define signal(2) as returning a pointer to a
function returning 'void'. K&R C signal(2) signature is obsolete.
Use 'void' directly.
Also, instead of writing the function pointer type explicitly, use
POSIX's 'sighandler_t'.

As autoconf documentation says, this macro is obsolescent, as no
current systems have the bug in S_ISDIR, S_ISREG, etc..
The affected systems were Tektronix UTekV, Amdahl UTS, and
Motorola System V/88.

INTERACTIVE Systems Corporation Unix is no longer sold, and Sun

So this macro has been obsolete for more than a decade.

it's likely that it is always available.
POSIX.1-2008 marks it as obsolete, but only because
clock_gettime(2) provides more precission. Since gettimeofday(3)
is in use by many big projects, and it has no obvious dangers,
it's likely that it will continue to exist even if it's outside of
the POSIX standard.
