Feature regression in gcc: -M option not available in gcc-gfortran-4.4

Issue

• Feature regression in gcc: -M option not available in gcc-gfortran-4.4
• To reproduce the problem, create the following files:
• mtest.F:

#include "mtest.h"
        x(1) = 2
        print 10, x(1)
10     format(' Hello World, x(1) =', i5)
        end

• mtest.h:

        integer x(10)

• Run the following command:

root@gncc mtest # gcc -M mtest.F

• The output with gcc-4.4 is:

f951: warning: command line option "-M" is valid for C/C++/Java/ObjC/ObjC++ but not for Fortran

• This was not the case with RHEL-5 and earlier:

root@gncc mtest # gcc -M mtest.F
mtest.o: mtest.F mtest.h
