gps status is a new variable.  Try git head to see if you problem still

nav_thread.cpp is not one of the gpsd programs.  If you want someone
to look at it, send the entire file and instructions to build it.

Minimal is a bad idea.  But without knowing your use case, hard to say
exactly why.

Which ignores most of the possible STATUS_ values.
