The error is on the declaration of the Stk::swap16 function.  Is it
possible this word swap16 is a macro somewhere in the BSD headers?  It
seems to be perhaps replacing the word swap16 with __swap16md_x, but I
have no idea why.
What do you see with "grep -r swap16 /usr/include" ?

The unterminated #if errors don't make much sense to me.
