This port is for ILE (native OS/400) not PASE (PASE is almost like Unix, and already comes with openssl). The idiosynchrasies are explained in the README.as400 file in AS400patch.tar.gz.

Again, the patch is smaller than the one for 1.1.1d one because EBCDIC fixes in 1.1.1e duplicated a part of my patch. AS400_GNU.tar.gz (source for GNU/IBM tools required to build openssl in ILE environment): https://drive.google.com/open?id=1DeKIE32nmUpvk7fvrcSYlflUn_k1CBso
