        * builtins.c (expand_builtin_interclass_mathfn): Provide a
        generic fallback for isinf.
        * c-cppbuiltin.c (builtin_define_float_constants): Move FP max
        calculation code ...
        * real.c (get_max_float): ... to here.
        * real.h (get_max_float): New.

testsuite:
        * gcc.dg/pr28796-1.c: Add more cases.
        * gcc.dg/pr28796-2.c: Likewise.
