Migration of Serialization macro

[timemarkov]

Hi All,
I have to migrate C++ source which is compiled with MinGW-gcc to be compiled with VS2013, and have one issue with one macro used for serialization.
Here is macro:

#define IMPLEMENT_SERIALIZE(statements)    \
    unsigned int GetSerializeSize(int nType, int nVersion) const  \
    {                                           \
        CSerActionGetSerializeSize ser_action;  \
        const bool fGetSize = true;             \
        const bool fWrite = false;              \
        const bool fRead = false;               \
        unsigned int nSerSize = 0;              \
        ser_streamplaceholder s;                \
        assert(fGetSize||fWrite||fRead); /* suppress warning */ \
        s.nType = nType;                        \
        s.nVersion = nVersion;                  \
        {statements}                            \
        return nSerSize;                        \
    }                                           \
    template<typename Stream>                   \
    void Serialize(Stream& s, int nType, int nVersion) const  \
    {                                           \
        CSerActionSerialize ser_action;         \
        const bool fGetSize = false;            \
        const bool fWrite = true;               \
        const bool fRead = false;               \
        unsigned int nSerSize = 0;              \
        assert(fGetSize||fWrite||fRead); /* suppress warning */ \
        {statements}                            \
    }                                           \
    template<typename Stream>                   \
    void Unserialize(Stream& s, int nType, int nVersion)  \
    {                                           \
        CSerActionUnserialize ser_action;       \
        const bool fGetSize = false;            \
        const bool fWrite = false;              \
        const bool fRead = true;                \
        unsigned int nSerSize = 0;              \
        assert(fGetSize||fWrite||fRead); /* suppress warning */ \
        {statements}                            \
    } 

Here is place in code were it is call (in class declaration):

IMPLEMENT_SERIALIZE(({
        if (!fRead) {
            uint64 nVal = CompressAmount(txout.nValue);
            READWRITE(VARINT(nVal));
        } else {
            uint64 nVal = 0;
            READWRITE(VARINT(nVal));
            txout.nValue = DecompressAmount(nVal);
        }
        CScriptCompressor cscript(REF(txout.scriptPubKey));
        READWRITE(cscript);
     });)

When compile received errors:
main.h(555): error C2059: syntax error : '{'
main.h(555): error C2143: syntax error : missing ';' before '{'

line 555 is end of macro call ( "});)").

So i need help how to correct call to the macro and avoid this errors.

Thanks in advance
