You could compile with -gnatwe to treat warnings as errors. This may
be beyond what you are looking for :-)

On the whole,most people find it easier to go with what the compiler
wants (you could try gnatchop; it takes the units in an arbitrary
source file and outputs each unit in the "expected" file).
