Thanks Luigi for your answer. Before I'll try to do that, I have two questions:
does this means LuaTeX will work only under MinGW? And does it still enable me
to link the source to the svn version (since apparently you download a special
version of the source)? I tend to build quite often, and that's sometimes
crucial in case of bug fixes.

Best,
Paul
