On Solaris 8, 9, 10/SPARC, iov_base is of type caddr_t which is char *. The Sun C++ compiler errors with "Cannot assign void* to char*". Using a static case to override this. On Solaris 11, HP-UX, AIX, and RHEL, iov_base is void * so no issues there. This seems a rather hackish solution so open to something better.

Fix building on MinGW64 Windows

Mingw64 provides mstcpip.h and the build fails (redefinition) if the struct tcp_keepalive is redefined. Do not define the struct if __MINGW64__ is defined. Note that I had to manually pass the compile definition to cmake: -D__MINGW64__=1

norm_engine update with no encoder_base_t::has_data() dependency

cmake // fixed msvc dll output path

cmake: fix test_fork,  fix fragile code related to HAVE_FORK macro

* report from Richard Newton indicated previous solutions was not
  working on Windows

Add Visual Studio 2013 solution and build for (v120) of libzmq project.

cmake: fix test_fork

* was problem on debian/wheezy

Remove delays in test_connect_rid and destroy/recreate context between tests

Fixed wrong assert in zmq_recv

zmq_recv returns bytes count, not error code, so 'assert (rc==0)' behaved completely wrong

Add delays in test_connect_rid

fixed another missed norm_engine issue for non-norm build

Fix cmake build on windows & travis build.

added uncommitted norm_engine changes

Fixed comment

NORM protocol extension

Revert "Fixed potential SEGFAULT."

This reverts commit 79b81f48.
Was causing:

Assertion failed: destroyed (socket_base.cpp:154)
/bin/bash: line 5: 31344 Aborted                 ${dir}$tst

On TravisCI.
