When the code is compiled with the GNU C compiler,
and the ${../if/const:/name} macro is attached to a
function declaration or definition,
and the return value of that function is not affected by changes
to the observable state of the program and that function has
no observable effects on such state other than to return a value,
the ${../if/const:/name} macro shall permit the compiler to replace
subsequent calls to the function with the same argument values by the
result of the first call.
