Can you add some documentation to gfortran.texi. I think we need to make clear that for library extension, the flag used for compiling the main program is relevant. Additionally, I believe some of the extensions are always on while others are only enabled with a flag - if so, I think we should make the distinction clearer.

If std= was used at compile time for std=f95, f2003, f2008, set the default
delimiter to 'NONE' if not otherwise specified.
