NP: the current 3.5 should need NO special options to build on Windows.

Sigh. OS headers not including their own basic dependencies. Evil
practice even in C.

The winldap.h not being found usable should only prevent the LDAP
helpers being built, not a big issue perhapse.

The absence of mswsock.h is probably involved with those later build
errors. It usually contains a lot of definitions needed for the FD and
socket API. If you can find out what it requires to be icluded before
it in the .cc file, please let me know.

No idea at this point what the correct fix is here. There is a bit of
a catch-22 situation going on with fd_set. With any luck is and the
below might disappear once mswsock.h is found.

Fixed this one.

No to both questions.

A lot has changed in the Windows support since 3.3. The
Windows-specific code has had a lot of shuffling around and testing
under MinGW. You are the first Cygwin person to report anything about
issues in the post-3.3 versions.

The Cygwin situation is kind of being tracked in
http://bugs.squid-cache.org/show_bug.cgi?id=4073. If you can update
the bug report it would be a help.
