Yes, I paid attention that for suffix .f (and probably for .ada) gcc
and g++ behave identically only after I posted my response.

BTW, it seems to me that here behavior of gcc/g++ is different from
gfortran. If I am not mistaken, gfortran by default treats extension .f
as "old FORTRAN" and extension .f90 as "new Fortran". But I can be
wrong about it, New Fortran is not something I compile regularly and
old FORTRAN is not something that I compile ever.
