Tested x86_64-linux. Pushed to trunk.

Tests which check for feature test macros should use the no_pch option,
so that we're really testing for the definition being in the intended
header, and not just testing that it's present in <bits/stdc++.h> (which
includes all the standard headers and so defines all the macros).
