By that definition of "strict conformance" you're also arguing for
rejecting a program that includes <unistd.h>.
As far as the standard goes, whether <unistd.h> is accepted is
at best implementation defined. By that same token, accepting <types>
is implementation defined. If your documentation tells you that
configuring the compiler with TR support will include TR semantics,
that is it. Just like we do for C99 stuff. We don't reject programs
that happen to include <tgmath.h> just on the mere assumption that
-std=c++98 is specified.
