Are you confused with CVS here?  The version you modified against was
1.1.12:

revision 1.1.1.2
date: 1996/02/27 01:58:50;  author: pst;  state: Exp;  lines: +18 -10
Import updated Berkeley DB into CSRG branch

And, the diffs you made are: (cut-paste, so white space is screwed up)
nec:/usr/src/lib/libc/db/hash % cvs diff -u -r1.1.1.2 -r1.2 hash_buf.c
