If the package is part of the Cygwin Net Distribution, you can download it
with http://cygwin.com/setup.exe. Please also read http://cygwin.com.

Cygwin != Linux.
Cygwin is a POSIX emulation layer for Windows. It is not based on Linux code,
nor is it actually anything more than a DLL with many, many features. There
is no way to "map" a Cygwin version number to a Linux version number because
* there is no relation
* the Cygwin version number (e.g. 1.5.5) is the number of the Cygwin DLL, 
  not the distribution (comparable with Linux-2.4.x being the version number
  of the kernel).
* there is no relation
* there is no relation

You're talking about *distribution* versions here - there is no versioning
scheme for the Cygwin Net Distribution.
