Currently not possible to compile range-v3 with -fno-rtti flag set #1764

Adding -fno-rtti flag leads to fail the build with the following errors:

range-v3-src/include/range/v3/view/anyview.hpp:129:24: error: use of typeid requires -frtti , info(&typeid(rtti_tag))

range-v3-src/include/range/v3/view/any_view.hpp:135:58: error: use of typeid requires -frtti RANGESASSERT(obj && info && *info == typeid(rtti_tag)); ^ range-v3-src/include/range/v3/detail/config.hpp:63:23: note: expanded from macro 'RANGES_ASSERT'

define RANGES_ASSERT assert

I think when (static) RTTI is disabled, any_view shouldn't be provided.

Sounds reasonable also to me. This feature is not part of any of C++ standard, as I understand.
