 * FreeCalypso hack: the version of l1_confg.h in the Leonardo semi-src
 * sets AUDIO_TASK to 1 unconditionally, thus it appears that by the
 * time TCS211 came around, TI stopped supporting and testing the
 * sans-AUDIO_TASK configuration.  We do wish to support it in FreeCalypso
 * though.  Attempting to compile this module w/o AUDIO_TASK failed
 * because some preprocessor constant definitions were missing.
 * All 3 offending constants are defined in l1audio_const.h, but only
 * when AUDIO_TASK is enabled.  The following hack is our workaround.
