*  Use -fPIC to support sparc/sparc64 architectures.
*  Removed the local portaudio header files.
*  Use the system's sonic library and header files.
*  Output phoneme compilation errors to stderr.
*  Generate build failures if building phoneme, intonation or dictionary files
   contain errors.

   implementation in a single place.
*  Replaced the audio APIs with PCAudioLib to improve portability of the audio

   audio.

cleanup:

*  Removed unused/empty internal header files.
