--- Comment #7 from Eric Gallager <egall at gwmail dot gwu.edu> ---
Another way to make deprecation warnings less noisy would be to split
-Wdeprecated-declarations into separate individually controllable flags, for
example, one that only warns about where the "deprecated" attribute is used
with the optional string following it. It could be called
-Wdeprecated-declarations-with-reasons or something, and then it'd make it
easier just to focus on the deprecated things for which there are replacements.
Another way to split it up would be by whether it's deprecated with the
C++-style attribute [-Wc++-deprecated-declarations] or a GNU-style attribute
[-Wgnu-deprecated-declarations]. Just focusing on one or the other might be
easier than trying to deal with warnings from each at the same time. Then
there's also splitting it by the kind of declaration, similar to how -Wunused
is an umbrella warning for several other more specific flags.
