The line it's complaining about in WINNT.H seems odd to me. The same
case compiled with gcc causes a warning:

x.c:11: warning: unnamed struct/union that defines no instances

#if defined(MIDL_PASS)
typedef struct _LARGE_INTEGER {
#else // MIDL_PASS
typedef union _LARGE_INTEGER {
    struct {
        DWORD LowPart;
        LONG HighPart;
    };                 <<<<<<<<<<<<<<<<<<<< Line 199
    struct {
        DWORD LowPart;
        LONG HighPart;
    } u;
#endif //MIDL_PASS
    LONGLONG QuadPart;
} LARGE_INTEGER;

I don't believe this problem is precipitated by anything in
pthreads-win32. Perhaps the LEDA code is causing the midl stuff
(something to do with double longs?) to be included.
