@item --with-diagnostics-color=@var{choice}
Tells GCC to use @var{choice} as the default for @option{-fdiagnostics-color=}
option (if not used explicitly on the command line). @var{choice}
can be one of @samp{never}, @samp{auto}, @samp{always}, and @samp{auto-if-env}
where @samp{auto} is the default. @samp{auto-if-env} means that
@option{-fdiagnostics-color=auto} will be the default if @code{GCC_COLORS}
is present and non-empty in the environment, and
@option{-fdiagnostics-color=never} otherwise.
