This revision now requires changes to proceed.

I've already stated my disapproval of this patch. Libc++ has never and will never provide nor value C++03 conformance.
Moving backwards to C++03 is inconsistent with the libraries general direction.

This patch disables tests, which could hide bugs, including serious ABI differences between dialects.

I would like to unbreak compilation on NetBSD. But all that's needed there is to provide our own correct declaration of max_align_t.
I don't see why C++03 conformance is a necessary condition.

If you would still like to proceed in this direction. Please remove me as a reviewer.

================
Comment at: libcxx/test/libcxx/language.support/support.dynamic/libcpp_deallocate.sh.cpp:156

+#if TEST_STD_VER >= 11
 #if defined(NO_SIZE) && defined(NO_ALIGN)
----------------
It's important these tests continue to pass in C++03.
