Seems this was correct, but these other header files still have errors.

Maybe the steghide developers, more familiar with the code, have a  
more informed context to share.

Any more ideas?

This issue seems to be the same as Buckley Collum wrote about on  
steghide-devel on 10 July 2005.

Perhaps it's part of the same GCC 4.x problem?  Perhaps it's  
something else unique to OSX / Darwin?
