[sqlite] Can I use both libraries?

[Marco Bambini]

Hi,
I have to develop an application that can use both sqlite2 dbs and 
sqlite3 dbs.
I have compiled fine both the libraries and my trial code looks like:

#include <stdio.h>
#include "sqlite.h"
#include "sqlite3.h"
int main(int argc, char *argv[])
{       
        int             err;
        sqlite  *ver2;
        sqlite3 *ver3;
        char    path2[]="trial2.db";
        char    path3[]="trial3.db";
        
        ver2 = sqlite_open(path2, 0, NULL);
        if (ver2!=NULL)
        {
                // Ok for version 2
                sqlite_close(ver2);
                return 2;
        }
                
        err = sqlite3_open(path3, &ver3);
        if (err==SQLITE_OK)
        {
                // OK for version 3
                sqlite3_close(ver3);
                return 3;
        }
        return 0;
}
Now the troubles ....
both sqlite.h and sqlite3.h begins with:
#ifndef _SQLITE_H_
#define _SQLITE_H_
...
#endif
so only one header is included and the other (the latest) is ignored.
A possible solution should be to change sqlite3.h with:
#ifndef _SQLITE3_H_
#define _SQLITE3_H_
...
#endif
but now, when I am trying to compile my application I have a lot of 
'macro/identifiers redeclared' errors...

For example:
macro 'SQLITE_VERSION' redefined
or
identifier 'sqlite_callback' redeclared
or
macro 'SQLITE_TEXT' redefined
and so on...
Any solution?
I really need to use both libraries in my project...
Thanks a lot.
