*Purpose:
*       Executes a file with given arguments.  Passes arguments to _execve and
*       uses pointer to the default environment.
*
*Entry:
*       _TSCHAR *filename        - file to execute
*       _TSCHAR **argvector - vector of arguments.
*
*Exit:
*       destroys calling process (hopefully)
*       if fails, returns -1
