* a shared library is built, no audio driver is included * implemented some platform specific functions (fluid_sys.*) * a test app is provided in fluidsynth.c * on target Haiku, posix mutex are used, else mutexes are implemented with simple semaphores (I could be wrong here) well I hope it can provide a good enough backend for a softsynth Note that needed SF2 banks would probably not be included. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17799 a95241bf-73f2-0310-859d-f6bbb57e9c96
