OK.  I withdraw the proposal.  All I know is what I read in the
readily available docs (info/man).  The -Wconversion doc says
nothing about intended use.  I just knew that it would help
identify value-modifying conversions (per your NewWconversion page).

So, I'll use -Wconversion iff GCC >= 4.3.  Thank you. -Bruce
