- Merge 4.4BSD strerror.3 man page changes that summarize information for all the error printing functions. This makes the perror(3) page obsolete. - Implement all error functions in terms of strerror_r(), including __strerror() which is not used internally. Can it be removed? - Bump version for strerror_r
