Jakub- Sorry, yes. I've had other priorities the past few weeks here,
but I just committed r266745 adjusted for -fdec-include.

Sorry again for the delay. It is committed now, so you may use the
new-style option setting. Thanks in advance for your upcoming patches.

The first comment (above set_default_std_flags) is also present before
gfc_init_options, which is technically the routine that should mirror
init_compile_options. Since set_default_std_flags is a subroutine of
gfc_init_options, it should also sync with the std flags setting in
init_compile_options, so I don't think any of the comments are
incorrect. However the symmetry may be more obvious if the std flags
setting from init_compile_options was in a subroutine (named similarly
to set_default_std_flags), then the comments on the default standard
flags could reference each other.

That being said, it does appear the default standard flags are out of
sync, as you mentioned... Not sure if this is worth a PR but it's
certainly worth fixing. Seems it was introduced when f2015 was renamed
to f2018 in r255761.
