it isn't deployed yet. gpsd can wait for newer C lib releases to break
its build, or it can get ahead like every other project i've sent patches
to and fix their source trees now.
this isn't specific to Linux either. it's long been an issue for other
OS's which is why autoconf has had a macro for this for more than a
decade. see AC_HEADER_MAJOR:
