process.c has this fragment after it calls 'connect':

  #ifdef NON_BLOCKING_CONNECT
  #ifdef EINPROGRESS
	if (is_non_blocking_client && xerrno == EINPROGRESS)
	  break;
  #else  <<<<<<<<<<<<<<<<<<<<<<<<<<<<
  #ifdef EWOULDBLOCK
	if (is_non_blocking_client && xerrno == EWOULDBLOCK)
	  break;
  #endif
  #endif
  #endif

Can someone tell why we need that "#else" there?  Suppose there's a
platform that has both values defined, but only returns EWOULDBLOCK
when a non-blocking 'connect' is called -- that platform will fall
through the cracks here.

Is there any problem to replace #else with #endif here?
