How about this approach then:

• To keep it simple, we update the README.rst to say that a minimum gcc-4.3 is required, while recommending gcc-4.9 for all architectures
• Support for gcc-4.0 and earlier gets removed from linux/compiler.h, and instead we add a summary of what I found, explaining that gcc-4.1 has active users on a few architectures.
• We make the Makefile show a warning once during compilation for gcc earlier than 4.3.

This sounds good to me!
