[gpsd-dev] [PATCH 2/3] Enable Windows version of gpxlogger

[Robert Norris]

Disable daemonize option which is not available on Windows.

Add check for signal compatibility as SIGQUIT may not be available.

TESTED:
Confirmed gpxlogger for Windows builds under a cross compiler.
Runs on a Windows system, connects to an instance of gpsd and produces a
 GPX file from the gpsd output.
gpxlogger still builds, runs on Linux including the daemon option
