All dev &/or build environments in which I've worked require that
compilation is clean i.e. self-evidently no errors and definitely no
warnings, so if warnings are expected in the build, is there a
definition/listing of them in order that they (the expected warnings)
may be safely discounted, thus allowing effort to be concentrated on
those that are unwanted/unexpected?
