	* exec.c (do_exec): Fix conditional for cleaning up INTERP,

	* exec.c (check_section): If the format makes no sense, return

	* hashexec.c (check_hashbang): When using executable name found on
	the path, don't return alloca()ed memory from search_path(); use
	malloc() instead.
	Use envz_get() to search the environment.

	* exec.c (S_exec_exec): Use envz_get() to search the environment.
