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.
Again, IANAL.
