I tried the recepies below myself and they worked for me, but it does not mean they all work for you as well :)

How to install Cygwin on Windows XP

Follow this http://cygwin-xp.portfolis.net/

Briefly:

• you need setup-x86.exe version 2.874.
• run setup-x86.exe -X to prevent signature verification
• add http://cygwin-xp.portfolis.net/cygwin to the mirror list

Note, latest versions of setup-x86[_64].exe don't work on XP, even though you run it with --allow-unsupported-windows option you will not able to install Cygwin, because mirrors list will be empty. If you try to add either normal http://cygwin.mirror.constant.com or mirror with old versions from above http://cygwin-xp.portfolis.net/cygwin installation will fails anyways.
