There is a movement to make the code base compile clean with W=1. Some subsystems are already clean. In order to keep them clean, we need developers to build new code with W=1 by default in these subsystems.
This patchset refactors the core Makefile warning code to allow the additional warnings W=1 adds available to any Makefile. The Ethernet PHY subsystem Makefiles then make use of this to make W=1 the default for this subsystem. RFT since i've only tested with x86 and arm with a modern gcc. Is the code really clean for older compilers? For clang?
