[zeromq-dev] Statically compiling libzmq on Windows

Hi again,

we are compiling static binaries of zeromq and link them into our executables. On windows, that means that I always open up zmq.h and zmq_utils.h to edit the part with regard to DSO symbol visibility as follows:

#ifndef ZMQ_STATIC
#if defined _WIN32
#   if defined DLL_EXPORT
#       define ZMQ_EXPORT __declspec(dllexport)
#   else
#       define ZMQ_EXPORT __declspec(dllimport)
#   endif
#   if defined __SUNPRO_C  || defined __SUNPRO_CC
#       define ZMQ_EXPORT __global
#   elif (defined __GNUC__ && __GNUC__ >= 4) || defined __INTEL_COMPILER
#       define ZMQ_EXPORT __attribute__ ((visibility("default")))
#   else
#       define ZMQ_EXPORT
#   endif
#define ZMQ_EXPORT

then adapt the build type in the Visual Studio project and pass ZMQ_STATIC as a preprocessor flag. The issue popped up on this list earlier as well [1][2]. The question is, whether you'd want the ZMQ_STATIC handling contributed to the master branch or is there another supported approach I missed? I cannot see how to make a test-case for this one though.
