Some implementations (e.g. glibc) require that, while implementations
that are fine with 5 of them still work the same (just with one more
constant letter)
Fix many -Wint-conversion errors such as the example below, including
an aso atomics error.
connect.c:87:12: error: incompatible pointer to integer conversion initializing 'LONG' (aka 'int') with an expression of type 'void *' [-Wint-conversion]
DB_ADDR mdba = NULL; /* db address of current member record */

This has meant very little for a long time as configure.ac just
hardcoded these values depending on the current OS versions at the
time.
The only place where this is really 'needed' is XlationSvc.c in DtSvc
so that differences between locale specifications on various versions
of an OS can be accounted for. So for now, we just define those when
building DtSvc.
We could probably safely remove them as well with an update to the
Xlate locale DB to remove ancient cruft we don't care about anymore.
For various other modules, like dtlogin, dtsession, etc we just use
the code that was already being used due to the hardcoded values we've
had for the last 10-ish years.
OS_VERSION was used with a '#if defined(sun)', but since it was never
set anywhere it just omitted that block. If the block turns up to be
broken on sun systems, then someone will fix it properly.
Previously we would fail in some parts of the code if we did not have a
premade configuration, now we use any code that was marked as Linux, BSD and
Solaris as our basis in order to support building unknown Unix systems.
Ticket #120
Change libtool's shared library version info to 3:0:1 to preserve the
previous library version of 2.1.0.
See https://autotools.io/libtool/version.html for the details on how
libtool handles this versioning info.
See https://verbump.de/ for a handy 'version calculator' using
libtools rules.
