This patch speeds up the Boost wave preprocessor by 1% and also improves
runtimes of the DLV testsuite by the same margin while reducing text-size
over a wider variety of libstdc++ users.

Bootstrapped and tested on x86_64-unknown-linux-gnu.

Ok for mainline?

I'm guilty of having rushed Richard to post this patch (sorry!), which, in general, I like indeed. However, it has to wait a bit for us (v3 maintainers) to carefully weigh the delicate points raised in the discussion thread with Hans about volatile & single-thread & signals... Thanks for the patience, Richard.

Paolo.
