As of now, there is no build system included with openjazz, which makes compiling and using it on Linux kinda hard. Attached is a patch that adds a simple traditional autotools-based buildsystem. It doesn't do all the necessary checks yet, but it's something. Doing "make install" with this is useless as of now because openjazz looks for data/configuration in the current directory, instead of the proper locations. Patches changing that will probably follow. Run autogen.sh to generate configure and Makefiles, then proceed as usual. You can create tarballs for release by running "make dist". The patch also changes USE_MODPLUG in src/io/sound.cpp to HAVE_LIBMODPLUG because that's what autoconf defines by default when it finds the lib. It also corrects the header location to what libmodplug actually uses. Tested on my Gentoo setup, seemed to work fine. I used 0.1 as the version in configure.ac, correct that to whatever you think is right if you want to.
