The egcs-1.0.2 for mingw32/cygwin32 has the packed attribute (can't
remember who sent in the fix -- Earnie was it?).


typedef struct tagBITMAPFILEHEADER {
  ...
} __attribute__((packed)) BITMAPFILEHEADER;

Please try it out.

btw, there have lots of fixes to the headers supplied with egcs-1.0.2,
so you should definitely consider upgrading.
