You will not be able to compile this file correctly without gcc, because
     it is necessary to pack the "wavefront_alias" structure to a size
     of 22 bytes, corresponding to 16-bit alignment (as would have been
     the case on the original platform, MS-DOS). If this is not done,
     then WavePatch-format files cannot be read/written correctly.
     The method used to do this here ("__attribute__((packed)") is
     completely compiler dependent.
     
     All other wavefront_* types end up aligned to 32 bit values and
     still have the same (correct) size.

#else

/* However, note that as of G++ 2.7.3.2, g++ was unable to
	correctly parse *type* __attribute__ tags. It will do the
	right thing if we use the "packed" attribute on each struct
	member, which has the same semantics anyway.

Because most/all of the sample data we pass in via pointers has
  never been copied (just mmap-ed into user space straight from the
  disk), it would be nice to allow handling of multi-channel sample
  data without forcing user-level extraction of the relevant bytes.
  
  So, we need a way of specifying which channel to use (the WaveFront
  only handles mono samples in a given slot), and the only way to do
  this without using some struct other than wavefront_sample as the
  interface is the awful hack of using the unused bits in a
  wavefront_sample:
  
  Val      Meaning
  ---      -------
  0        no channel selection (use channel 1, sample is MONO)
  1        use first channel, and skip one
  2        use second channel, and skip one
  3        use third channel, and skip two
  4        use fourth channel, skip three
  5        use fifth channel, skip four
  6        use six channel, skip five

This can handle up to 4 channels, and anyone downloading >4 channels
  of sample data just to select one of them needs to find some tools
  like sox ...

NOTE: values 0, 1 and 2 correspond to WF_CH_* above. This is 
  important.
