realmax and realmin were renamed to floatmax and floatmin in Julia 0.7.0 (JuliaLang/julia#28302). Support for them was added in #525:

julia> using ForwardDiff

julia> floatmax(typeof(ForwardDiff.Dual{Float64}(1.)))
Dual{Float64}(1.7976931348623157e308)

julia> floatmin(typeof(ForwardDiff.Dual{Float64}(1.)))
Dual{Float64}(2.2250738585072014e-308)
