Rewrite the Compiler detection tests for deprecation and unused.
Simplify and make more safe, clang or compilers supporting __has_extension()
and __has_attribute() should work perfectly. There are now GCC version
tests for all these features, however there seems to be some disagreement
online about which GCC versions introduced these features, so I picked the
versions that I felt had the highest consensus. Can revisit the specific
versions if new information is available:
unused attribute: GCC 3.1 (BSD seems to think 2.7)
deprecated attribute: GCC 3.2 (Hedley seems to think 4.0)
deprecated with message attribute: GCC 4.5
