	- Norman Kraemer added an ALSA sound driver. It can be used 	  if you disabled OSS emulation in your ALSA configuration. 	- Norman Kraemer changed the software renderer to check the 	  commandline for the -sounddriver option. If that ain't 	  given, the configuration will be checked for Sound.Driver 	  entry to contain a sounddriver to use. If that fails as 	  well, the default system driver (CS_SOUND_DRIVER) is tried. 	- Norman also changed unix.mak to include the alsa plugin if           available as well as the configure.ac to check for the alsa           requisites.
