ok, i've focused this down a bit more, and here's the problem. one
of the patches brought forward and applied to 4.2.8p13 is to add a
new flag to sntp/sntp-opts.def, where a flag has the format:
flag = {
name = unprivport;
value = u;
descrip = "Use an unprivileged port";
doc = <<- _EndOfDoc_
Use an unprivilegded UDP port for our queries.
_EndOfDoc_;
};
as long as the patch that adds that new flag is not applied, things
build fine. and if one looks at the top of that file as it comes with
ntp-4.2.8p13, one reads:
autogen definitions options;
#include autogen-version.def
argh.
so, as i read it, if you modify that file, you will automatically
kick in the requirements for autogen, which is exactly what i am
trying to avoid.
am i making sense? is there an alternative approach to doing this
that removes the need for autogen?
