The problem with a warning is that people might be building with
-Werror. If they do that and they also have the deprecated flag in
their Makefile, their builds fail.
But telling users that their build flags have no effect is IMHO a good thing.
Proposal: We could add a "Deprecated" option property to common.opt,
and use "inform()" to tell users they are using a deprecated option.
If this sounds acceptable to y'all, I will craft a patch to implement
it.
(I couldn't find if this was proposed before. "inform()" is quite
new, and I don't know if it was around already when it was first
discussed what to do with removed options.)
