            Bug ID: 92830
           Summary: -fdiagnostics-url shows the wrong URL for warnings
                    which are not in 'gcc' but e.g. in 'gfortran'
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
                CC: dmalcolm at gcc dot gnu.org
  Target Milestone: ---

Cf. also PR 87488

Create a file 'test.f90' with:
!-----------
print *, "Hello &
   world"
end
!-----------

And run it:  gfortran -Wall test.f90

This will show:

Warning: Missing ‘&’ in continued character constant at (1) [-Wampersand]

With the link:
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wampersand

However, that's the wrong file. The correct link is:
https://gcc.gnu.org/onlinedocs/gfortran/Error-and-Warning-Options.html#index-Wampersand
