Then you've still got a problem with sizeof(boolean), I'd bet,
or else a structure packing rule (#pragma pack).  Are you sure
you recompiled everything affected by the header files you changed?

It might help to #include jpeglib.h *before* including any Windows-
specific headers... if one of their headers is leaving #pragma pack
in a nondefault state, that could cause this problem.
