为什么在语法正确的情况下VS2010会出现语法错误？

// Prototype Declarations
LIST*   createList     (int (*compare) (void*, void*));
LIST*   destroyList    (LIST* plist);
int     addNode      (LIST* pList, void* dataInPtr);
bool    removeNode      (LIST* pList, void* keyPtr, void** dataOutPtr);
bool    searchList      (LIST* pList, void* pArgu, void** pDataOut);
bool    retrieveNode    (LIST* pList, void* pArgu, void** dataOutPtr);
bool    traverse        (LIST* pList, int fromWhere, void** dataOutPtr);
int     listCount    (LIST* pList);
bool    isListEmpty     (LIST* pList);
bool    isListFull      (LIST* pList);

bool found;
