The patch is almost fine, except for a strange wording here:

+@smallexample
+gfortran -save-temps -c foo.F90
+@end smallexample
+
+preprocesses to in @file{foo.fii}, compiles to an intermediate
+@file{foo.s}, and then assembles to the (implied) output file
+@file{foo.o}, whereas:

I understand the formulation is copied from gcc/doc/invoke.texi,
where it does not fully make sense to me either.

How about:

"preprocesses input file @file{foo.F90} to @file{foo.fii}, ..."

Furthermore,

+@smallexample
+gfortran -save-temps -S foo.F
+@end smallexample
+
+saves the (no longer) temporary preprocessed file in @file{foo.fi}, and
+then compiles to the (implied) output file @file{foo.s}.

Even if this is copied from the gcc texinfo file, how about:

"saves the preprocessor output in @file{foo.fi}, ..."

which I find easier to read.

Can you also add a reference to the PR number in the commit message?

Can you be more specific?  I get here (since gcc-9):

% man /opt/gcc/14/share/man/man1/gfortran.1 |grep -A 1 "Interoperability 
Options"
        Interoperability Options
            -fc-prototypes -fc-prototypes-external

although no detailed explanation (-> gfortran.info).
