Not only those, but apparently also ::size_t or std::plus; this broke
FAIL: g++.dg/cpp1y/feat-cxx14.C   (test for excess errors)
FAIL: g++.dg/cpp1z/feat-cxx1z.C  -std=gnu++17 (test for excess errors)
FAIL: g++.dg/cpp1z/pr85569.C  -std=c++17 (test for excess errors)
FAIL: g++.dg/cpp2a/feat-cxx2a.C   (test for excess errors)

Fixed thusly, tested on x86_64-linux with check-c++-all, ok for trunk?

	PR testsuite/90772
	* g++.dg/cpp1y/feat-cxx14.C: Use std::size_t instead of size_t.
	* g++.dg/cpp1z/feat-cxx1z.C: Likewise.
	* g++.dg/cpp2a/feat-cxx2a.C: Likewise.
	* g++.dg/cpp1z/pr85569.C: Include <functional>.
