  When argument ${../if/alias:/params[0]/name} is a name of a function,
  and the macro ${../if/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/alias:/name}(oldname)``;,
  and the ``<return-type>`` and ``argument-type-list`` match the
  signature of the function ``oldname``,
  and the code is compiled with the GNU C compiler,
  the ${../if/alias:/name} macro shall cause the compiler to create
  an additional name (``newname`` in the syntax) for the function
  given as argument ${../if/alias:/params[0]/name}.
