Ok.
When code is multi-licensed it must be distributed under *all* these
licensing terms concurrently. It is easy to understand. Removing (or
changing) the conditions that apply to the program from the source code
and documentation *without* an authorization from all the author(s) is
illegal.
So, a multi-licensed file remains multi-licensed except when all authors
agree about a change in the licensing terms. And it is clear on the BSD
license that a modification of the distribution terms is illegal. It is
the first clause on the BSD license:
* 1. Redistributions of source code must retain the above copyright
* notice, this list of conditions and the following disclaimer,
* without modification.
So, removing (or changing) the list of conditions on the BSD license is
not allowed.
