Reini, I'm afraid you've totally misunderstood what Charles is saying. The 
"GREAT PAIN" is taken by library package maintainers, to produce libfooX, 
libfooY, libfooZ, so that as a package ages, old ABI DLLs are still 
available. That email has absolutely nothing to do with the sequencing of 
dependencies during setup operations. Setup has no special logic like you 
allude to. The only reason we see it mainly for cygwin1.dll is because is is 
such a core dependency.
