options are given a full integer.
@item NoDriverArg
For an option marked @code{Separate}, the option only takes an
argument in the compiler proper, not in the driver. This is for
compatibility with existing options that are used both directly and
via @option{-Wp,}; new options should not have this property.
@item Var(@var{var})
The state of this option should be stored in variable @var{var}.
The way that the state is stored depends on the type of option:
