The file is dual licenced under both the GPL and the BSD licence, the
restrictions the BSD license places on the usage is a subset of the
restrictions the GPL places on it.

If the file is used under the terms of the GPL then it is also be
being used under the terms of the BSD license (because anything you can
do under the GPL you can do under the BSD), so everything is fine.

If someone tries to use the file in a way that is acceptable to the BSD
license, but not to the GPL license then the file cannot be used
without removing the GPL'ed parts.

So both license have to be mentioned, but usage is resricted by the
most restrictive license (the GPL) and the extra freedoms granted by
the BSD license are lost.
