Well, there are lots of things that gfortran does that I find confusing, and I've contributed to some of it. ;) > It think that a more accurate description > would start with: > > -pedantic: Issue warnings for some uses of extensions to Fortran, raise > otherwise warnings to errors for others.

Yes, it sounds bad, but at least reflects reality. -pedantic is not really pedantic. > 3) If this is the intended behaviour I can propose some tweaks > to the documentation, but as I said first I would like to have > a confirmation (ideally by the person who set up the interaction > between -pedantic and -fallow-argument-mismatch) that this is > really intended behaviour, not accidental.

Given the lack of volunteers to maintain gfortran at the moment, the best path forward may be an attempt to clarify the option descriptions. After years of contributing to gfortran, I have come to the conclusion that all extensions should require options to permit them. -std=gnu would activate the options; while, any other -std=... would de-active all of the extensions and issue errors. But, that ship has sailed.
