--- Comment #41 from Lorenzo Ferrillo lorenzofer@live.it --- IT may be that old versions of MWSE will still initialize if the 3 functions are not found.
However MWSE wil fail badly when trying to use mods that use functions that manipulate Morrowind's heap. (so the symbol.c hack would be still needed)
The version I tried would actually bail out at the first not found function, preventing Morrowind to start at all.
Also newest nightly build actually hardcode the function address, after a report about this issue on MWSE side.
