[Bug fortran/24784] Warning about unused routine argument should not read "unused variable"

[dfranke at gcc dot gnu dot org]

------- Comment #3 from dfranke at gcc dot gnu dot org  2006-11-30 22:34 -------
In addition to comment #2, it is to note, that "-W" alone does not give any
diagnostic at all. 

Also, the FE emits different messages, if different flags are specified:
# -Wall
Warning: Unused variable x declared at (1)
                ^^^^^^^^
# -Wall -W
Warning: Unused parameter x declared at (1)
                ^^^^^^^^^
