I'm not a lawer too, but I did some research on license types when
choosed which one to use for my libs. And I'm definitely sure that
any BSD code may be used in GPL (and many other) code. It's
one of most permissive lecenses.
Here is a wikipedia link:
http://en.wikipedia.org/wiki/License_compatibility
So, putting a code under "weaker" (BSD) and "stronger" (GPL)
license together looks... awkward... I.e. that's possible, but useless.
