Build Error while enable output compress about joy

[flat2010]

Original:

// output.h
#else
    /** gzip compressed output */
    #include <zlib.h>
    typedef gzFile zfile;

    #define zopen(fname, ...)    (gzopen(fname, __VA_ARGS__))

    #ifdef WIN32
        #define zattach(FILEp, ...)  (gzdopen(_fileno(FILEp), __VA_ARGS__))
    #else
        #define zattach(FILEp, ...)  (gzdopen(fileno(FILEp), __VA_ARGS__))
    #endif

    #define zprintf(output, ...) (gzprintf(output, __VA_ARGS__))
    #define zflush(FILEp)        (gzflush(FILEp))
    #define zclose(output)       (gzclose(output))
    #define zsuffix              ".gz"
#endif

My fix:

// output.h
#else
    /** gzip compressed output */
    #include <zlib.h>
    typedef gzFile zfile;

    #define zopen(fname, ...)    (gzopen(fname, __VA_ARGS__))

    #ifdef WIN32
        #define zattach(FILEp, ...)  (gzdopen(_fileno(FILEp), __VA_ARGS__))
        #define zflush(FILEp)        (gzflush(FILEp))
    #else
        #define zattach(FILEp, ...)  (gzdopen(fileno(FILEp), __VA_ARGS__))
        // here we  pass Z_FINISH to gzflush
        #define zflush(FILEp)        (gzflush(FILEp, Z_FINISH))
    #endif

    #define zprintf(output, ...) (gzprintf(output, __VA_ARGS__))
    #define zclose(output)       (gzclose(output))
    #define zsuffix              ".gz"
#endif
