First before I get your hopes up. Cygwin maps many errors to EAGAIN which is outputed as Resource Temporarily Unavailable.
The one I am referring to is win error 234 (ERROR_MORE_DATA) that Christopher Faylor recently changed to report error "Message Too Long". The root cause was that our environment block was greater than 32K characters. Some script in our build flow was defining 29000 characters worth of environment variables which made us hit the Windows ANSI string limit. Microsoft recommended that we use the unicode CreateProcess and specify CREATE_UNICIODE_ENVIRONMENT flag, this would allow cygwin not to hit this 32K limit. Thought I would put it to the list, to see if anyone has investigated this, or has any reasons as to why we shouldn't do this.
