The source package is called "3" only because I could not rename it to just
"zeromq", since that name is still used. The idea being that zeromq should be
removed as soon as nothing uses it anymore, and zeromq3 renamed to zeromq.

As for the 3 in the binary packages (libzmq3, libzmq3-dev, ...), that simply
reflects the library SONAME as per Debian policy. Having a zeromq4 source
package would not have changed anything, since its binary package would still
have to be named libzmq3.

In your case the check should be "#if ZMQ_VERSION_MAJOR < 3", since 4.x is
backwards-compatible with 3.x.

Cheers
