timezone: long vs char*

[Joseph S. Atkinson-5]

Hello. I was working on bringing audio/liboggz up to date in ports, but hit a
snag. liboggz expects timezone information to be long, which is (I am told) in
accordance with SUSv3. FreeBSD is appears to be returning char*.

I asked about this in #bsdports and was told that it appears that FreeBSD is
wrong in this case and should be fixed. I saw no mention of this as a known
issue on the standards webpage.

I think the people on "#bsdports" (an IRC channel, I assume) are
wrong.  FreeBSD has never targeted conformance to any version of SUS,
which memorializes a large number of UNIX System V's historic
mistakes.  We do target conformance to POSIX (IEEE Std. 1003.1-2008 is
the current version).

In the POSIX specification, the declarations of "timezone" and
"daylight" in <time.h> are flagged as "XSI", meaning that they are
part of the X/Open System Interfaces extension, which in turn means
that they are part of SUS but not POSIX.

Well, these days the SUS and POSIX standards are pretty much the same thing.

If the POSIX specification specifies them they are very much part of POSIX,
but in this particular case an optional part of POSIX.
