For Linux, it can't happen.  For systems which follow the Principle of
Least Astonishment and have the PPS API calls on the serial fd, I am
pretty sure one can -- aside from that one-line assumption -- just use
the documented API.

But, this is fixed.  I added ifdefs so that the special Linux code (line
discipline, groveling in /sys for the pps name, opening it) is only
compiled on Linux.   Systems other than Linux assume that the serial fd
is the one to use, and I believe that's true on every other system that
supports RFC2783.
