same remarks, today only this:

for(WORD j = 0; (pMD = pClass->m_MethodList.PEEK(j)); j++)
{
...
    EATEntry* pEATE;
    /*
        struct	EATEntry
        {
            DWORD	dwStubRVA;
            DWORD	dwOrdinal;
            char*	szAlias;
        };    
    */
    ...
    m_EATList.PUSH(pEATE);
