Browse Source 
The header file contains lots of outdated comments and definitions.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.
