The header file contains lots of outdated comments and definitions.
Drop those as cleanup.

     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.
