Which "actual solution" are you asking about? If you're asking if there 
is an approved/supported way to build OpenLDAP using Cygwin, the answer 
is no. Nor is there any interest in providing it.

As I noted in that previous email, Cygwin tries to duplicate a Unix 
environment. When you setup OpenLDAP to build "properly" using Cygwin, 
none of the Windows-specific code in OpenLDAP gets used; everything gets 
done the plain old Unix way and the Cygwin library adapts it where 
necessary.

The problem is, there are a number of serious bugs in Winsock itself 
that are triggered when you do things the plain old Unix way. That is 
why there is Winsock-specific code in the OpenLDAP source, so that we 
can explicitly work around those bugs. If you're using Cygwin with 
OpenLDAP, you'll run into those bugs, leading to race conditions and 
resource leaks inside Winsock because Cygwin itself has to use Winsock 
to get its job done.

The Cygwin support in OpenLDAP isn't missing because we didn't finish 
it. It's missing because we got there, saw that it performed miserably, 
and decided that it's not worth doing again.
