I did not see any precedent in the sources for using those to test for features by compiling particular test sources (i.e. in autoconf style). I just followed the model I saw. Those methods seem sufficiently costly to make it a little questionable to pile on too many more that get repeated all the time by make, so I just was not opening that can of worms. As has been mentioned: #if __GNUC_MINOR__ > 4 is a sufficient test for the long run. People using Fedora gcc-4.4 will not mind applying a trivial kernel patch to get the benefits sooner.
