* Traits containing basic integer limits. Useful for template-based
* code on platforms that lack @c std::numeric_limits<>.
*
* @note These traits are not meant to be a replacement for
* @c std::numeric_limits<>. Rather they are a crutch until all
* ACE-supported platforms also support
* @c std::numeric_limits<>.
*
* @internal Only meant for internal use by ACE.
* @deprecated This header will be removed once all platforms
* supported by ACE support @c std::numeric_limits<>.
