There may well be a problem with MOPS since the bug you reported is
still there. The issue that I raised previously, that ntp_config.c is
part of ntpd and not part of ntp-keygen may be indicative of the issue.
Without reading the code, something is not right, since, if it concludes
that msktemp() is dangerous then it should have hooked it into ntpd as a

You may want to have the code look at the Makefile to figure out what a
source file is consumed by. ntp-keygen was not one of them, hence my
I'm in the process of cleaning up other issues before I take another
look at this.
