ntpd/ntp_control.c, I'm guessing look for _OFFSET

That note shows the author apparently applying POSIX knowledge
inappropriately to Windows.  Arguably, the issue is with OpenSSL not
net-snmp, but both are at risk of having development dominated by
folks less than fluent in Windows development.  There is no problem
installing multiple OpenSSL versions used by multiple apps on Windows,
when done properly, which is to day putting the DLLs in the directory
containing the the executable.  One can choose to install openssl DLLs
in systemwide directories if leaving behind Windows 3.1's DLL Hell is
just too much change to process, I suppose.

It's less than encouraging about the amount of effort required to use
net-snmp on Windows.  So far we have a single monolithic build setup
on Windows without configure options such as --with-net-snmp or
whatever.  That means the straightforward way to add use of net-snmp
would provide another barrier to entry to building the reference
implementation on Windows from source.  In addition to a working
compiler, openssl headers and libraries, we'd need net-snmp headers
and libraries.  Given how little ntpsnmpd is used on the
far-more-prevalent POSIX ntpd systems porting it to Windows is pretty
far down my list.
