[gpsd-dev] [PATCH]: Guard NTPSHM-related declarations

[Matt]

These functions aren't called if ntpshm support is disabled, so there's 
no need to declare them.
Fixes the following warning seen on cygwin with ntpshm disabled:

In file included from gpsutils.c:22:0:
gpsd.h:1215:80: warning: 'struct shmTime' declared inside parameter list
 extern int ntpshm_put(struct gps_device_t *, volatile struct shmTime 
*, struct timedrift_t *);
^
gpsd.h:1215:80: warning: its scope is only this definition or 
declaration, which is probably not what you want
