Thorsten Schöning commented on LOGCXX-400:
------------------------------------------
CASTing itself doesn't seem to be entirely wrong as well:
{quote}G++ 4.6 gave an error but it was changed to a warning intentionally for
4.7 because many people (myself included) found that narrowing conversions
where one of the most commonly encountered problems when trying to compile
large C++03 codebases as C++11. Previously well-formed code such as char c[] =
{ i, 0 }; (where i will only ever be within the range of char) caused errors
and had to be changed to char c[] = { (char)i, 0 }{quote}

> C++11 does not allow char literals with highest bit set unless cast

> C++11 has tighter rules for widening of literals. In particular, 0xFF (for
> example) is an unsigned short unless cast otherwise.
