This can be handled simply by providing two implementations of printf,
which can be selected at link time.  Another possibility would be to
require something like Unix's "-Dformat=APW_format" for programs being
ported from the old version to the new version, where the APW_format
function implements the old printf semantics.  Or you could have a
compiler option that specifies whether you want compatible or ANSI
semantics (it could predefine a bunch of such macros).
