Hi,

with current-source updated some minutes ago new ntpd fails
to compile on i386

    compile  ntpd/ntp_control.o
/u/NetBSD/src/external/bsd/ntp/dist/ntpd/ntp_control.c: In function 'ctl_putdata':
/u/NetBSD/src/external/bsd/ntp/dist/ntpd/ntp_control.c:804:25: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]

   currentlen = MIN(dlen, dataend - datapt);

cc1: all warnings being treated as errors

*** Failed target:  ntp_control.o

This is no problem on amd64, fwiw.
