Andreas, more seriously, if you mean that __CHAR_BIT__ can be != 8, I
don't think we are *really* supporting that kind of non-Posix target
anyway in the C++ runtime. And here we are talking only about C++1x
features. Anyway, do you think I should write something like:
(80 + __CHAR_BIT__ - 1) / __CHAR_BIT__
instead of 10?
Not a big deal...
Paolo.
