/*
    Changes: 
    07/12/03  moved openSocket to it's own file, because it can be reused in other TCP clients
    04/07/04  ported C++ version to C
    12/17/04  additonal defines for WIN32
    04/09/05  removed CYGWIN defines. As there were no more differences against LINUX, it should 
	      work with LINUX defines.
Version 0.8.4.5    
    07/10/09  	Added closeSocket()
