Hi I've committed a few small small fixes to oowintool, mostly for JDK 8 detection and better logging, but I've confirmed that it already works well, and --with-frame-home --with-psdk-home --with-midl-path --with-jdk-home --with-csc-path and --with-cl-home options to ./configure are all unnecessary.
As for 64 bit Cygwin I believe the problem with oowintool is that it needs to look under the Wow6432node subkey in the registry too, something that should be easy to add. Is anyone available to test 64 bit Cygwin? Damjan
