 * --------------------------------------------------------------------------------------
 * 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

     * member information is stored in a data structure at offset
     * indicated by the memoffset field of the typeinfo structure
     * There are several distinctive parts.
     * The first part starts with a field that holds the total length
     * of this (first) part excluding this field. Then follow the records,
     * for each member there is one record.
     *
     * The first entry is always the length of the record (including this
     * length word).
     * The rest of the record depends on the type of the member. If there is
     * a field indicating the member type (function, variable, interface, etc)
     * I have not found it yet. At this time we depend on the information
     * in the type info and the usual order how things are stored.
     *
     * Second follows an array sized nrMEM*sizeof(INT) with a member id
     * for each member;
     *
     * Third is an equal sized array with file offsets to the name entry
     * of each member.
     *
     * The fourth and last (?) part is an array with offsets to the records
     * in the first part of this file segment.
