24 * --------------------------------------------------------------------------------------
25 * Known problems (2000, Francois Jacques)
26 *
27 * - Tested using OLEVIEW (Platform SDK tool) only.
28 *
29 * - dual interface dispinterfaces. vtable-interface ITypeInfo instances are
30 * creating by doing a straight copy of the dispinterface instance and just changing
31 * its typekind. Pointed structures aren't copied - only the address of the pointers.
32 *
33 * - locale stuff is partially implemented but hasn't been tested.
34 *
35 * - typelib file is still read in its entirety, but it is released now.
36 *
37 * --------------------------------------------------------------------------------------
38 * Known problems left from previous implementation (1999, Rein Klazes) :
39 *
40 * -. Data structures are straightforward, but slow for look-ups.
41 * -. (related) nothing is hashed
42 * -. Most error return values are just guessed not checked with windows
43 * behaviour.
44 * -. lousy fatal error handling
45 *
