+       rint: Determine RINT_LIBM correctly on AIX 7.
+       * m4/mathfunc.m4 (gl_MATHFUNC): Try to invoke the function also
+       directly, not only through a function pointer. Also accept an optional
+       4th argument with extra code.
+       * m4/rint.m4 (gl_FUNC_RINT): Pass an extra code that gets turned into a
+       rintf() call by gcc when optimizing.
+
        mathfunc.m4: Refactor.
        * m4/mathfunc.m4 (gl_MATHFUNC): Assign the argument list to a temporary
        m4 variable.
