**      Macros are necessary to map standard sockets calls, which set the
**      errno global variable as a side effect of the call, to our
**      implementation-specific library entry points which expect to receive
**      a pointer to the errno variable.  This is required since (1) the
**      custom memory model sockets library can't set a global variable
**      in the user's application without receiving a pointer to it (which
**      would require a sockets-interface change), and (2) global variables
**      are not available between dynamic link libraries and user applications.
**
**      These macros transparently provide full errno functionality without
**      requiring sockets source code changes.
