I still don't see the point. The advertising clause was removed ten
years ago and the remaining 3 clauses impose just a few restrictions.

You can choose any license for code owned by you. You can also
relicense BSD-licensed code, but you still must either obey the
original license or obtain written permission to change the terms
[from the original copyright owner, University of Californa and
USL/Novell, not the FreeBSD project]. Take a look at

If you are writing your own version of errno.h then it is not a
derived work. In this particular case, errno.h is just a list of error
codes so you can copy/paste the numbers and mnemonics from the output
of "man 2 intro". That would be considered "compatible code", not
derived work. Please refer to the last two paragraphs of the
"Pretrial" section at
http://en.wikipedia.org/wiki/USL_v._BSDi#Pretrial

May be you could just accept the current license and avoid the pain. ;-)

My preferred quotation of Robert Louis Stevenson is "You cannot
make an omelette without breaking eggs". Not because I like the
omelettes, but because I like the sound of eggs being broken.
