    * updated old and not longer valid comment

  * harbour/source/vm/memvars.c
    * minor code formatting

    % added support for buffering hb_stack TLS access be preloading
      the stack pointer into C stack function local variables.
      Please make speed tests for MT mode with different C compilers
      and different platforms.
