It's those major changes.... Certainly, any change my code sees, like
STATUS_DGPS_FIX going away somewhere between API version 5.01 and 6.1.
(I seem to have missed 6.0 entirely.) Pull and look at gnome-gps.c line
978 et seq..

Maybe I should just get rid of the 5.01 support and the compile time
version checks. Now that I have it under git, anyone silly enough to
want to support 5.01 can check out an appropriate tag.

OK. It also appears to work across a network where I have a 7.0 server
feeding a 6.1 client.

Meanwhile gpsd continues to support my ancient BU 353 like a charm. You
guys do good work! Thanks!
