Annex C (informative) Compatibility [diff]

Change: Remove auto as a storage class specifier.

Rationale: New feature.

Effect on original feature: Valid C++ 2003 code that uses the keyword auto as a storage class specifier may be invalid in this International Standard.

In this International Standard, auto indicates that the type of a variable is to be deduced from its initializer expression.

Change: Narrowing restrictions in aggregate initializers.

Rationale: Catches bugs.

Effect on original feature: Valid C++ 2003 code may fail to compile in this International Standard.

For example, the following code is valid in C++ 2003 but invalid in this International Standard because double to int is a narrowing conversion:

int x[] = { 2.0 };
