These are just the GPL releases, but they contain bits of code from EA if you start digging. IIRC the EAWebKit release contains a big chunk of EASTL. EASTL is EA's implementation of the C++ STL that was for a long time considered so great as to be a competitive advantage.

If anyone is interested in the EASTL here's the source code

https://github.com/paulhodge/EASTL

Apparently works out of the box with G++/GCC, some modifications were made to get it working Clang/LLVM
