How do we handle the Sun Copyright for derivative works.

[Steve Munroe]

How do we handle the Sun copyright in glibc code when we patch or 
copy/modify such code. For example 
./sysdeps/ieee754/dbl-64/s_logb.c.

1) Leave the Sun (C) and add 2005 date?
2) Leave the Sun (C) and add the LGPL header with 2005 date?
3) ?
