Any time you insert sleep calls into something means you have a timing 
issue and are just masking the real problem, which will probably show 
itself in a different way later.

I'll defer to the Cygwin devs for real analysis, though.

Downloading the whole tool chain for that release of Cygwin might work 
better for you.  Also, there is a specific build process for Cygwin 
documented on the website, that I believe someone else already replied to 
you about.  If not, search the mail archives.

Probably.  Why not?

I emailed you privately with the process to pull all of that release + 
source.  I never heard back from you and my logs don't seem to show any 
access to the paths for that release.  If you have further problems 
downloading it, please email me privately.
