+The @code{alias} variable attribute causes the declaration to be emitted

+for top-level qualifiers the alias target must have the same type as
+the alias.  For instance, the following

+defines @code{var_alias} to be an alias for the @code{var_target} variable.
+
+It is an error if the alias target is not defined in the same translation
+unit as the alias.

+Note that in the absence of the attribute GCC assumes that distinct
+declarations with external linkage denote distinct objects.  Using both
+the alias and the alias target to access the same object is undefined
+in a translation unit without a declaration of the alias with the attribute.

+This attribute requires assembler and object file support, and may not be
