 * --------------------------------------------------------------------------------------
 * Known problems (2000, Francois Jacques)
 *
 * - Tested using OLEVIEW (Platform SDK tool) only.
 *
 * - dual interface dispinterfaces. vtable-interface ITypeInfo instances are
 *   creating by doing a straight copy of the dispinterface instance and just changing
 *   its typekind. Pointed structures aren't copied - only the address of the pointers.
 *
 * - locale stuff is partially implemented but hasn't been tested.
 *
 * - typelib file is still read in its entirety, but it is released now.
 *
 * --------------------------------------------------------------------------------------
 *  Known problems left from previous implementation (1999, Rein Klazes) :
 *
 * -. Data structures are straightforward, but slow for look-ups.
 * -. (related) nothing is hashed
 * -. Most error return values are just guessed not checked with windows
 *      behaviour.
 * -. lousy fatal error handling
