Cygwin build documentation error.

["Aaron Gray" <angray at beeb dot net>]

I am getting errors on building Cygwin. It appears to be something to do 
with the documentation.

Am I missing something simple such as a package like cygwin-doc and if so 
where do I get it ?

Error text below...

Many thanks in advance,

Aaron
