 *      For functions which are either STUBs or WSTUBs the actual function
 *      need to be called using 'call' instruction because of preamble and
 *      postamble (i.e mod_hold_stub and mod_release_stub) around the
 *      function call. Due to this we need to copy arguments for the
 *      real function. On Intel we can't tell how many arguments are there
 *      on the stack so we have to either copy everything between esp and
 *      ebp or copy only a fixed number (MAXNARG - defined here) for
 *      all the stub functions. Currently we are using MAXNARG (it is a kludge
 *      but worth it?!).
 *
 *      NOTE: Use NO_UNLOAD_STUBs if the module is NOT unloadable once it is
 *            loaded.
