I checked the FAQ and did numerous searches both on your website and
Google, but could not find any mention of Cygwin being section 508

Can you please let us know if the latest version of Cygwin is compliant
with Section 508 of the Rehabilitation Act?  If possible, please provide
us a completed Voluntary Product Accessibility Template (VPAT).
