same type as the variable it is initializing.
@item
If @code{signed} or @code{unsigned} is omitted, the vector type defaults
to @code{signed} for @code{vector int} or @code{vector short} and to
@code{unsigned} for @code{vector char}.
If @code{signed} or @code{unsigned} is omitted, the signedness of the
vector type is the default signedness of the base type. The default
varies depending on the operating system, so a portable program should
always specify the signedness.
@item
Compiling with @option{-maltivec} adds keywords @code{__vector},
