If i implement a simple socket client, that is not so much of an issue, because I call the functions separately and can handle the error. Moreover in this case bind() is not necessary.

Therefore I think best is to set the port number to zero (port = 0) before the call to bind().

Hi Raimund,
Where, exactly, would you set the port number to zero?  I can imagine how this 
would solve the problem you're seeing but I'm concerned about other use cases.

It also seems a little odd to me we'd be making a Cygwin-specific patch rather 
than "fixing" Cygwin itself so the patch would not be necessary.  But I don't 
feel strongly either way here.  libtirpc already has Cygwin-specific patches.
