No, I don't have that kind of information.  However, I can say that the 
Cygwin function (cygwin_getservbyname()) is just a wrapper that calls
the Winsock getservbyport() function.  So, the MSDN may have some information
regarding this function and Winsock which may be applicable to your situation.
Then again, it may not. ;-)

Sorry I don't have more specific suggestions for you.
