-@item c1x
-ISO C1X, the draft of the next revision of the ISO C standard.
-Support is limited and experimental and features enabled by this
-option may be changed or removed if changed in or removed from the
-standard draft.

@item gnu90
@itemx gnu89
GNU dialect of ISO C90 (including some C99 features). This
GNU dialect of ISO C99. When ISO C99 is fully implemented in GCC,
this will become the default. The name @samp{gnu9x} is deprecated.
-@item gnu1x
-GNU dialect of ISO C1X. Support is limited and experimental and
-features enabled by this option may be changed or removed if changed
-in or removed from the standard draft.

@item c++98
The 1998 ISO C++ standard plus amendments. Same as @option{-ansi} for
C++ code.
language-specific options also refer to @ref{C++ Dialect Options} and
@ref{Objective-C and Objective-C++ Dialect Options}.
-When an unrecognized warning label is requested (e.g.,
-@option{-Wunknown-warning}), GCC will emit a diagnostic stating
-that the option is not recognized. However, if the @samp{-Wno-} form
-is used, the behavior is slightly different: No diagnostic will be
-produced for @option{-Wno-unknown-warning} unless other diagnostics
-are being produced. This allows the use of new @option{-Wno-} options
-with old compilers, but if something goes wrong, the compiler will
-warn that an unrecognized option was used.

If you really need to change the search order for system directories,
use the @option{-nostdinc} and/or @option{-isystem} options.
-@item -iplugindir=@var{dir}
-Set the directory to search for plugins which are passed
-by @option{-fplugin=@var{name}} instead of
-@option{-fplugin=@var{path}/@var{name}.so}. This option is not meant
-to be used by the user, but only passed by the driver.

-@opindex maccumulate-outgoing-args
-Reserve space once for outgoing arguments in the function prologue rather
