Not really, but thanks for your suggestion.
My Java native components are usually compiled under Visual C++. As I
provide them as Free Software, I would like to provide a way to compile
this components without having to use a proprietary compiler. This is why
I went for 'Cygwin', but 'Cygwin', and especially the 'Cygwin' DLL, isn't
required for my components to work.
