That assumes you have a correct limits.h on the system, which is an assumption you can't necessarily make on an old enough system.Do you have any specific examples here, found outside of a museum? Current Autoconf more or less tells users to assume C89 for new programs, and limits.h exists in a free-standing implementation, too.
My own software does not currently depend on limits.h but tests I did separately on many types of systems (including several 12 year old ones) with a program which specifically exercises limits.h (including 'char') did not encounter any problems.
