Expecting this as exported as fundamental_type_info, see in emit_support_tinfos
via rtti.c:1461:

  static tree *const fundamentals[] =
  {
    &void_type_node,
    &boolean_type_node,
    &wchar_type_node, &char16_type_node, &char32_type_node,
    &char_type_node, &signed_char_type_node, &unsigned_char_type_node,
    &short_integer_type_node, &short_unsigned_type_node,
    &integer_type_node, &unsigned_type_node,
    &long_integer_type_node, &long_unsigned_type_node,
    &long_long_integer_type_node, &long_long_unsigned_type_node,
    &int128_integer_type_node, &int128_unsigned_type_node,
    &float_type_node, &double_type_node, &long_double_type_node,
    &dfloat32_type_node, &dfloat64_type_node, &dfloat128_type_node,
    &nullptr_type_node,
    0
  };

Which should take care of this, given the libstdc++ ver patch to export the
symbols. However, none is emitted when building
libsupc++/fundamental_type_info.o.

Ouch.
