I would not notice it, as the C++/Flex/Bison input codes I use are small,
which I test on short inputs (not large computer PL input files and the
like).
I think though that early C++ compilers were not so efficient, so that
might have produced slow code relative C. If that was the problem, more
recent C++ compilers should not have it.
