... and only *define* them in the source files that need them. Use DEFINE_OR_DECLARE which is set appropriately for internal builds and not non-deprecated builds. Deprecate stack-of-block Better documentation Move some ASN1 struct typedefs to types.h Update ParseC to handle this. Most of all, ParseC needed to be more consistent. The handlers are "recursive", in so far that they are called again and again until they terminate, which depends entirely on what the "massager" returns. There's a comment at the beginning of ParseC that explains how that works. {Richard Levtte} Reviewed-by: Dmitry Belyavskiy <beldmit@gmail.com> Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/10669)
