Found it: you need to enable HAVE_PPSAPI in config.h. Then you need to
include some includefile in a couple of files to get it compile.

But then:
ntpd is running
keetweej:/usr/src/linuxpps-current# ntpq -c pe
keetweej:/usr/src/linuxpps-current# ntpq -c pe
     remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================
+GENERIC(0)      .DCFa.           0 l   16   64    3    0.000    4.703   0.291
 PPS(0)          .PPS.            0 l    -   64    0    0.000    0.000   0.001

then i run ppstest:
keetweej:/usr/src/linuxpps-current# test/ppstest
found PPS source #0 "pps_8250_0" on "/dev/ttyS0"

that is incorrect! the gps is connected to ttyS1
kernel with latest patch from git
i also tried with the ktimer client-module instead of ntpd, same result
