Problem: Recent deprecation of the "zmq_utils.h" header file caused pedantic compilations (including czmq) to fail because non-portable #warning is used. Solution: Limit the deprecation warnings to compilers known or assumed to support the "#pragma message" (GCC, MSVC, CLANG) and wrap with GCC directives to not treat these warnings as errors on paranoid builds.
