Hi all,
here is a patch that I had submitted already in February (see
https://gcc.gnu.org/ml/fortran/2016-02/msg00011.html). Unfortunately
it was never approved and I got distracted with other things and
forgot about it.
It's a diagnostics patch, which makes sure that the responsible flag
is printed in several warning messages (for which this was still
missing). As a small extra the patch also mentions the -Wpedantic flag
in the gfortran documentation.
Fortunately the patch still applies cleanly and regtests without
failures on x86_64-linux-gnu. Ok for trunk?
Cheers,
Janus
