--- versions of the Appendix C string handling packages. One change is
--- to avoid the use of Is_In, so that we are not dependent on inlining.
--- Note that the search function implementations are to be found in the
--- auxiliary package Ada.Strings.Search. Also the Move procedure is
--- directly incorporated (ADAR used a subunit for this procedure). A
--- number of errors having to do with bounds of function return results
--- were also fixed, and use of & removed for efficiency reasons.
