[gpsd-dev] [PATCH] Bump GPS_PATH_MAX to allow using persistent names.

The current value of GPS_PATH_MAX works for /dev/ttyfoo, but is slightly 
too small to allow using persistent dev names. For example, an ND-100S 
also shows up on my machine as 
/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0, 
which requires GPS_PATH_MAX >= 82.

I'm aware of gpsd.rules, but it seems convenient not to require the use 
of additional udev rules.
