@opindex fms-extensions
Unless @option{-fms-extensions} is used, the unnamed field must be a
structure or union definition without a tag (for example, @samp{struct
@{ int a; @};}). If @option{-fms-extensions} is used, the field may
also be a definition with a tag such as @samp{struct foo @{ int a;
@};}, a reference to a previously defined structure or union such as
@samp{struct foo;}, or a reference to a @code{typedef} name for a
previously defined structure or union type.
