On Windows, I don't think our (new) Ant projects need Cygwin or Windows System for Linux to open in Eclipse after AOO is built.

It's easy to overlook the vastness and complexity of our existing build systems, after all we have custom toolchains doing custom localization, custom configuration, custom testing, custom "javadoc"-like documentation, custom everything. Porting *those* to something else is **hard**, and even the gbuild migration didn't try to do that. Also those custom makefiles/tools/scripts needs awk, Perl, grep, sed, zip, and other *nix utilities themselves, hence also the need for Cygwin... > All the best > Peter > > > Damjan
