I'm confused.  Corinna, does your statement mean that the code in
autoload.cc is correct as it is now (which is the same as it was at the
time this email was written) --- or does autoload.cc need to be
"corrected" to unreverse the ws32_handle and wsock32_handle tests?  
(I'm going through my cygwin inbox trying to tie up some open threads
w.r.t "my" packages)
