This is a known bug in gcc - it does not pack structures correctly when
compiling C++.  The easiest way to work around this is to surround dir.h
with the following:

#pragma pack(1)
#include <dir.h>
#pragma pack()

I suppose you could also edit dir.h to insert the pragma lines in the
#ifdef __cplusplus sections.

This question is going to be in the next release of the FAQ, which is coming
RSN.  :)
