Consider the following Fortran code:
subroutine s(x)
real :: x
integer :: i
end subroutine
Compiling this with "gfortran-4.3 -Wunused-variable" triggered two warnings:
Warning: Unused variable 'i' declared at (1)
Warning: Unused dummy argument 'x' at (1)
With recent trunk builds the first one is missing, and only the missing dummy
argument is detected. This seems to be a Fortran-specific problem, since unused
variables in C code are reported as expected.
Observed on x86_64-unknown-linux-gnu with rev. 140091.
