Your code was corrupted by your emai client. I cleaned it up, fixed
a warning. Works for me. See attached.
My gpsd is built locally from git head.
My gpsd is started this way: gpsd -n /dev/ttyS0
cgps says I have a good fix.
Here is how I built and ran it. Sorry for the run together:
# gcc test.c -lgps -o test
# ./test
latitude: 44.068688, longitude: -121.314101, speed: 0.392819,
