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 revision of C++.

In this revision of C++, 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 revision of C++.

For example: int x[] = { 2.0 };

This code is valid in C++ 2003 but invalid in this revision of C++ because double to int is a narrowing conversion.
