[zeromq-dev] Checking for Win platform?

That's one option. It would require anyone compiling an application to
define WIN32 (even under MinGW or so).

The other option would be to include zmq_platform.h from zmq.h,
zmq_platform.h having a single line:

#define ZMQ_HAVE_WIN32

zmq_platform would be shipped in Win32 package. On other platforms
autotools can automatically generate zmq_platform.h. Say:

#define ZMQ_HAVE_LINUX

Similar thing to the Win32 trick would have to be done on OpenVMS
platform, where autotools are not available.

Not sure which option is better though...
