RFR: Some build fixes for gcc4.7

[Coleen Phillimore]

The changes to binaryTreeDictionary.cpp are already in the hotspot-gc 
repository and will/have been pushed up to main already. They should 
already be in hotspot-comp.

Which compiler complains about the library_call.cpp changes?  I have an 
unstable ubuntu 12.10 system in order to run with gcc 4.7.2 and this 
file compiles fine for me as is.

Thanks,
Coleen
