RE: [ANN] winapi 1.4

I fixed the problem with the changes I told you. I copy the code below.

However, I suppose that the 'text' field in the LuaCallParms structure in messages is always a (null terminated) string. Since the message system is only used for watch_for_file_changes in my application, it seems it works. However, I don't know if it's true for all the uses of your module.

free(P->text);
