Unless you are the copyright holder, you can't *change* the license of BSD3
code, either.

You can bundle BSD licensed code in a collective work which is released under
the GPL.  However, you cannot remove the license nor the copyright notice from
a BSD-licensed file.  You don't own the IP, you just have permission to use it
under the terms of the BSD license, which includes this provision:

    1. Redistributions of source code must retain the above copyright
       notice, this list of conditions and the following disclaimer.

This makes life challenging in a multi-licensing environment, since code
cannot move easily between files under different licenses.  Here is how the
Apache Software Foundation recommends that its projects handle differently
licensed code:


    4. Minor modifications/additions to third-party source files should
       typically be licensed under the same terms as the rest of the rest of the
       third-party source for convenience.

    5. Major modifications/additions to third-party should be dealt with on a
       case-by-case basis by the PMC.

At the ASF, though, we only deal with modifications to third-party files with
permissive licenses (MIT, BSD, Apache, etc).  Things get trickier when one of
the licenses is the GPL, because the GPL stakes its claim at the boundary of
"derivative work", and it takes effort to ensure that BSD code within a
project is in no way derived from any of the GPL code in the next directory
