i would say that as the author and copyright holder of the code, you
can license it however you want. you are not obligated to release it
under only one license, you can, for example, provide a copy of the
same code under the BSD license if you so desire.

if someone else wrote the code, and holds the copyright, you can
take it up with them.

if there are dozens of authors, it gets harder. but it's important to remember
that the BSD license and the GPL/LGPL licenses are _licenses_,
supplements to copyright, and the copyright holder has the power to make
the choice about the license.
