Yeesh; I did not know that.  Thanks for pointing that out. So that means there's 
another possible way to try solving the OP's issue: by using Cygwin's 
bindresvport* in place of the one supplied with libtirpc.

If we see the OP's issue with Cygwin's bindresvport*, I think it makes more 
sense to patch libtirpc than to change Cygwin's bindresvport*.  The crux of OP's 
issue is that libtirpc's code expects to see EADDRINUSE errors from bind() 
whereas on Cygwin they aren't often seen until you connect().

I'll look into using Cygwin's bindresvport() in the next day or two.
Thanks all,

..mark
