In my environment it applies to gcc, but not to g++.
In order to force my g++ to compile for other language you have to

No, g++ treats extensions other than ".c" the same way as gcc.  (I
tested to be sure this time!)  Try :
 
touch foo.f
gcc foo.f
g++ foo.f
 
You'll get the same complaint - either from missing Fortran support
or a failure to build the Fortran program.  Even "g++ foo.m" tries to
compile as Objective-C, not Objective-C++.
 

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.
