2018-08-21  Nicolas Koenig  <koenigni@gcc.gnu.org>
	Thomas Koenig <tkoenig@gcc.gnu.org>

	PR fortran/25829
	* gfortran.texi: Add description of asynchronous I/O.
	* trans-decl.c (gfc_finish_var_decl): Treat asynchronous variables
	as volatile.
	* trans-io.c (gfc_build_io_library_fndecls): Rename st_wait to
	st_wait_async and change argument spec from ".X" to ".w".
	(gfc_trans_wait): Pass ID argument via reference.

2018-08-21  Nicolas Koenig  <koenigni@gcc.gnu.org>
	Thomas Koenig <tkoenig@gcc.gnu.org>

	PR fortran/25829
