But I may have missed them too. > lib/msun/b_log.c and lib/msun/mathimpl.h have appear to have onlu UCB in file (other than bde and das in the RCS string). lib/msun/b_tgamma.c has a standard 4-clause BSD license with the years 1992 and 1993 listed. But, later in the file there is the comment /* * This code by P. McIlroy, Oct 1992; * * The financial support of UUNET Communications Services is greatfully * acknowledged. */ IANAL, so I don't know if this triggers the "and its contributors." portion of clause 3. lib/msun/b_exp.c has a standard 4-clause BSD license with the years 1985 and 1993 listed. Later in the file is KC Ng's ChangeLog like annotation /* EXP(X) * RETURN THE EXPONENTIAL OF X * DOUBLE PRECISION (IEEE 53 bits, VAX D FORMAT 56 BITS) * CODED IN C BY K.C. NG, 1/19/85; * REVISED BY K.C. NG on 2/6/85, 2/15/85, 3/7/85, 3/24/85, 4/16/85, 6/14/86.
