GPL never changes the license of anything, the only question is if its
GPL compatible or not, and as stated in FSF site the new BSD/MIT licenses
are GPL compatible and therefore can be used.
for example linking staticly to xlibs by a GPL app doesn't make xlibs
GPLed, and the other way around for BSD licensed program linking to GPLed
library. (I'm sure google would provide few examples).
