That seems to be a complaint of the C compiler, e. g.

$ cat tmp.h
typedef struct {
   unsigned long X;
   __int64 Y;
} abc;
$ gcc tmp.h
tmp.h:3:4: error: unknown type name ‘__int64’
    __int64 Y;
    ^

You can fix that with a 

typedef long long __int_64;

assuming long long is the correct replacement for __int_64, or include the 
header file where __int_64 is defined if such a header file exists.
