When the code is compiled with the GNU C compiler,
and the produced target file format is ELF or a.out,
and argument ${../if/weak-alias:/params[0]/name} is a name of a function,
and the macro ${../if/weak-alias:/name} call is in the same compilation unit
as the function,
and the macro is not used in block scope,
and the macro is used in this form:
``<return-type> newname([argument-type-list]) ${../if/weak-alias:/name}(oldname)``;,
and the ``<return-type>`` and ``argument-type-list`` match the
signature of the function ``oldname``,
and there is no other function symbol at global scope with the same name as
``newname``,
the ${../if/weak-alias:/name} macro shall cause the compiler to create
an additional name (``newname`` in the syntax) for the function
given as argument ${../if/weak-alias:/params[0]/name}.
