There was regression in FRUIT 2.9.
When Fortran source is updated and older corresponding object file exists,
rake did not recompile the source.

#### on FRUIT 2.9
rake sample_single_dir
cd sample_single_dir
touch mystack.f95
rake
# (here mystack.f95 is not complied)

It is fixed in the latest CVS version.

### Latest CVS version
rake sample_single_dir
cd sample_single_dir
touch mystack.f95
rake
# (here mystack.f95, mystack_test.f95, ... are re-complied. It's intended behavior.)
