  Don't include compiler-specific headers

Including anything in <bits/*> is not portable. Also, the contents of
this header were never used.

Stan Cox (scox@xxxxxxxxxx) reported:

It's not included as the first thing in the file, which means it can't
use the precompiled version of that header
(https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html) and
therefore it's just including the entire C++ standard library, which is
going to be much slower than just including the right headers.
