[Bug c++/45411] New: Please add "-Wno-unused-variable" and friends compiler warning options

["noloader at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hello,

"-Wno-unused-variable" and friends such as "-Wno-unused-parameter" would be
welcome additions for folks who like to use "-Wall" and "-Wextra".

Reasons it would be a good idea to include the "-no" forms:
(1) its easy to remember
(2) its easy to use
(3) when using "-Wall" and "-Wextra", the noise created by the various unused
warnings drowns out other issues which should get attention
(4) there's nothing intuitive about the 'unused' attribute so one might have to
actually RTFM
(5) I'm lazy and don't want to locate the applicable man page for the proper
usage of the 'unused' attribute
(6) the 'unused' attribute requires modifications to source files at all
applicable declarations (and non-use)
(7) makefile friendly solutions, such as "-Wno-unused-parameter", means one
only has to change one file
(8) I'm lazy and don't want to change every declaration with an 'unused'
attribute
(9) no easy way to control 'unused warning' spew is one of the biggest
complaints on the crypto++ mailing list when building for *nix
