[cfe-dev] -Wint-to-pointer-cast on by default?

[Ted Kremenek]

I noticed that -Wint-to-pointer-cast is covered by -Wall and -Wmost, but it also appears to be enabled by default.  Is this intended?

Looks like it was added in October:

I'm not objecting to it being on by default.  Just wanted to know if this was intended.
