these warnings are issued because XXX_r() functions are not available
for cygwin and the XXX() functions are not reentrant and threads are
enabled. So there is the chance that two threads call a non reentrant
function at the same time...

If you keep SNMPv3 enabled, you need (as Frank also wrote) libdes,
libtomcrypt or openSSL (for openSSL you will have to add -lssl or
something similar to the linker command of the examples).
