Make this build on 10.9: Apparently the std::deque header changed in the 10.9 SDK, breaking our code, so we hard-code 10.8 for now until I can find a fix.
Fix parsing of one-line ‘if’ statements without an ‘else’ clause. Our parser needs to leave the newline after its code in the token stream, yet we were skipping past it in that one case. Added testfile13.hc as an example that breaks without this fix.
