I have put up a few test builds of the current 2.3 branch to https://sourceforge.net/projects/warzon ... %20Builds/ (for the data, use svn or http://warzone2100.svn.sourceforge.net/ ... 7&view=tar). The -updated-libs have freetype, gettext, libogg, libpng, libvorbis, zlib updated to newer versions, -gcc444 are compiled with gcc 4.4.4, -gcc421 with gcc 4.2.1.
All those builds should behave the same, and a short test of -updated-libs-gcc444 turned up no problems that were caused by the build itself. I'm mainly interested in differences between those builds, most of the problems 2.3.0 had will still be there.
