I understood it to be in the opposite direction. The GPL apparently considers 
dynamic linkage to be derivation of the copyrighted work, but derivation 
has a definite direction.

A GPL application could link to or incorporate BSD/MIT code, but that BSD/MIT 
code could not link to or incorporate GPL code. Under section 2 of the GPL it 
seems to be okay as it is the distribution of the whole that must be under 
the GPL, not the individual "independent and separate works". However, 
section 3 says that all source code must be distribute under the terms of 
section 1, which says "publish on each copy an appropriate copyright notice" 
and "give any other recipients of the Program a copy of this License".

This is kind of confusing, as section 1 pertains only to the original work 
(verbatim copies), while section 2 pertains to derivative or collective 
works. So does section 3 mean to apply section 1 OR section 2 as appropriate, 
or is it saying that section 1 AND section 2 be applied to all parts 
regardless of whether they are original, derivative or collective?

Can a dual-licensed work be linked to GPL code if one of the licenses is not 
compatible with the GPL? This would be a pretty big loophole.
