I share Greg's opinion that this list is not the place for getting or
giving legal advice. Please _do_ consult a lawyer.
In my _personal_opinion_, dual licensing gives you the right to choose
between two licenses. If a file is dual licensed BSD/GPLv2, anybody
(including yourself) is free to get rid of the BSD part and make it
GPLv2 only.

Thanks,
