On Windows
When POCO_HAS_UNIX_SOCKET is usually not defined
Poco Net fails to build

In 'void HTTPSession::connect(const SocketAddress& address)'
line 'if (address.family() != SocketAddress::UNIX_LOCAL)'
Build fail because UNIX_LOCAL isn't defined and not protected by #if defined(POCO_HAS_UNIX_SOCKET)

In void SocketAddress::init(const std::string& hostAndPort)
line 'newLocal(hostAndPort);'
Build fail because newLocal methods are defined only if POCO_HAS_UNIX_SOCKET is defined, instead of guard the content of the methods.
