I think Dominique was referring to the documentation for the "regular people",
i.e., Sec. (4.3) from the gfortran manual, which is where his quote comes from,
and which was the quote that initially caused me to include -pedantic as one of
the flags that I (now previously) used when compiling with gfortran.

Sec. (4.3) should be changed so that

"Valid FORTRAN 95 programs should compile properly with or without this option.
However, without this option, certain GNU extensions and traditional Fortran
features are supported as well. With this option, many of them are rejected."

instead reads

"Not all valid FORTRAN 95 programs will compile properly when using this
option.  If you want to ensure compliance with one of the FORTRAN standards,
please see the -std= option."
