There's a lot of historical stuff in posix, for lots of reasons.  You
are saying "standard", but you are meaning "what the man pages on the
linux system in front of me stay", which is not what standard means.

See POSIX.  That is the standard, and if Linux is different Linux should
be fixed.  Absolutely gpsd needs to follow POSIX.  If that works ok on
Linux, it should just be like that.   If not, there needs to be a Linux 
workaround.
