 * SSE optimized functions for peak computation, buffer mixing and
   applying gain. These functions can be used on any x86 processor
   (except those running in 64 bit mode). To compile them in, be
   sure that BUILD_SSE_OPTIMIZATIONS=1 when building.

   When the routines are built in, ardour will check the processor
   features run-time and select them if the processor supports
   SSE. Look for a message "Enabling SSE optimized routines" in
   the console when starting up Ardour. If you do NOT see this
   message, it means that these optimizations have not enabled.

   Note to packagers: to make your life easier, we have tried to
   make it possible to compile ardour in whole without SSE
   BUT include these routines. To do this, set
      BUILD_SSE_OPTIMIZATIONS=1
        and
      USE_SSE_EVERYWHERE=0
  
   This builds ardour without SSE instructions, but it builds the
   optimized routines, checks for SSE at run-time and selects them
   if the current architecture can run them.

 * ardour/gtk: 0.602.1
   libardour: 0.899.0
