Michael,

I was having the exact same problem, and I managed to get around it by
editing the /usr/include/winnt.h system file (yikes!).

Basically, from line 2206, change this:

typedef struct _IMAGE_IMPORT_BY_NAME {
    WORD Hint;
    BYTE Name[1];
} IMAGE_IMPORT_BY_NAME, *PIMAGE_IMPORT_BY_NAME;

to this:

typedef struct _IMAGE_IMPORT_BY_NAME {
    unsigned short Hint;
    unsigned char Name[1];
} IMAGE_IMPORT_BY_NAME, *PIMAGE_IMPORT_BY_NAME;

It's not exactly proper however... but it works. My guess is it's a weird
bug in GCC, since those typedefs are used everywhere in the winnt.h file and
GCC only chokes on that one.

Cheers,
