Cross-platform primitive data types in C++

Question

Unlike Java or C#, primitive data types in C++ can vary in size depending on the platform. For example, int is not guaranteed to be a 32-bit integer. Various compiler environments define data types such as uint32 or dword for this purpose, but there seems to be no standard include file for fixed-size data types.

What is the recommended method to achieve maximum portability?

Answer 1

I found this header particularly useful: BOOST cstdint

Usually better than inventing own wheel (which incurs the maintenance and testing).
