This is little different than before.  Here's your code back, with the 
#defines in the right places.  Comments with *** in them on each line I 
added, or marking interesting things.  There are only 3:



// FILE main.cpp ///////////////////////////////////////

#define MYSQLPP_SSQLS_NO_STATICS // *** main.cpp doesn't own it
#include "ClassWithSSQLS.h"
int main()
{
    ClassWithSSQLS c;
    return 0;
}

// FILE ssqls.h //////////////////////////////////////////

#ifndef SSQLS_H
#define SSQLS_H

#include <mysql++.h>
#include <custom.h>

sql_create_2(   macro, 1, 0,
                unsigned int, id,
                unsigned int, key )
#endif

// FILE ClassWithSSQLS.h ////////////////////////////////////////////

#ifndef CLASSWITHSSQLS_H
#define CLASSWITHSSQLS_H

#define MYSQLPP_SSQLS_NO_STATICS // *** ditto ClassWithSSQLS.h

// H IS NOT OWNER BUT NEEDS TO HAVE macro IN SCOPE SO....
#include "ssqls.h" // << THIS LINE SPOILS THE PARTY :(

class ClassWithSSQLS
{
    public:
        ClassWithSSQLS();
        macro           macro_;
};

#endif

// FILE ClassWithSSQLS.cpp //////////////////////////////////////////

// *** No #define here, because ClassWithSSQLS.cpp *does* own it

// THE CPP IS THE OWNER!
#include "ClassWithSSQLS.h"

ClassWithSSQLS::ClassWithSSQLS()
{
   macro m;
}



One .cpp file as owner.  That's all.
