:REVIEWMAIL:

The attached is an updated patch against current trunk.  This patch revises the 
behavior as follows:

With no compile options (ie. -std=gnu or default) the expanded namelist read 
behavior is allowed.

With -pedantic a run time warning is issued using existing std_notify functions 
if a non-standard read occurs.

With -std=f95 a run time error is issued if a non-standard read occurs.

A review of the patch will show handling a few corner cases that resulted in 
emitting warnings when we should not.  These false warnings are avoided by 
setting the expanded_read flag to zero in those cases.

I have attached the test case that was submitted before.  I could have included 
a -pedantic on that and check for dg-output but I did not think I needed to test 
this in the test-suite since the std_notify function exists already and is tested.

OK to commit to trunk and then 4.1?

Regards,

Jerry

	PR libgfortran/24459
	* io/list_read.c (nml_parse_qualifier): Leave loop spec end value
	at default value unless -std=f95 or if an array section
	is specified in namelist input.  Warn if -pedantic.
