Re: Removing -Wunsuffixed-float-constants, -Wdouble-promotion, -Wformat-zero-length

[Karl Berry]

    1) The gcc manual doesn't list all warning flags.

    2) The gcc --help=warnings doesn't list all warning flags, although it
       is a different subset than 1).

How about reporting bugs about these things to gcc?

    3) Several of the warnings mentioned by gcc --help=warnings does not
       apply to C.

Could also say that a way to autoparse the warnings by language would
be helpful, and describe what we are trying to accomplish.
