SIGH. I was hoping a 32 bit cygwin with 32 bit self compiled programs will
run on 64 bit Windows, too. But I was wrong.
Meanwhile I have 4 VMs:
Windows 32 bit with 32 bit cygwin
Windows 32 bit with 32 bit cygwin for compiling
Windows 64 bit with 64 bit cygwin
Windows 64 bit with 64 bit cygwin for compiling

I have several 100 users, none of them is able to install cygwin and
the packages they need the official way, they are way to *CENSORED* for
this job :-} 
I give them my preconfigured cygwin.zip (or cygwin64.zip) and tell them to
unpack it in C:\


(This is what I call "transfer cygwin")

This works so far without problems.
