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:

Implement GCC's -Wint-to-pointer-cast.
This implementation doesn't warn on anything that GCC doesn't warn on with the
exception of templates specializations (GCC doesn't warn, Clang does). The
specific skipped cases (boolean, constant expressions, enums) are open for
debate/adjustment if anyone wants to demonstrate that GCC is being overly
conservative here. The only really obvious false positive I found was in the
Clang regression suite's MPI test - apparently MPI uses specific flag values in
pointer constants. (eg: #define FOO (void*)~0)
I'm not objecting to it being on by default. Just wanted to know if this was intended.
