The bridge.h header file needs extern C wrappers for the functions.  
I've updated the sample code with the new header file; hopefully  
there aren't other things that I missed. The new bridge.h file is:

#include <Carbon/Carbon.h>

#include "SYNCMGR.H"
#include "UserMgr.h"

#ifdef __cplusplus
extern "C" {
#endif

bool loadBridge(void);
void unloadBridge(void);

#ifdef __cplusplus
}
#endif

// Since our conduit gets unloaded, the normal CFSTR is referencing  
an object that can go away
#ifdef CFSTR
#undef CFSTR
#define CFSTR(x)  ::CFStringCreateWithCString( kCFAllocatorDefault,  
x, ::GetApplicationTextEncoding() )
#endif
