Bundling schema

Hi, Well, since people had some objections about removing Expat entirely. I decided to work on that bundling scheme I was talking about awhile ago. I have a commit pending that achieves this, initially by changing the expat extension. Essentially what it does is separate the bundling of expat itself with the xml extension. By creating ext/bundle and storing expat in ext/bundle/expat, I have the following options cleanly available: ./configure --disable-xml (disables the xml extension, but bundles expat) ./configure --disable-bundle-all (don't bundle any libraries) ./configure --enable-bundle-all (bundle all the libraries) ./configure (bundle defaults) ./configure --disable-bundle-expat --with-expat-dir=/usr/local/ (use the expat libraries in /usr/local/) If no one has any major objections, I'll commit this to cvs. -Sterling
