[expr.mul]
Change: Specify rounding for results of integer / and %.
Rationale: Increase portability, C99 compatibility.
Effect on original feature:
Valid C++ 2003 code that uses integer division rounds the result toward 0 or
toward negative infinity, whereas this International Standard always rounds
the result toward 0.
[expr.log.and]
Change: && is valid in a type-name.
Rationale: Required for new features.
Effect on original feature:
Valid C++ 2003 code may fail to compile or produce different results in
this International Standard, as the following example illustrates:
bool b1 = new int && false; // previously false, now ill-formed struct S { operator int(); }; bool b2 = &S::operator int && false; // previously false, now ill-formed
