I think the poisoning belongs in system.h; direct dependencies on the host compiler (such as GCC_VERSION and __GNUC__ tests) should be kept as local as possible, in just a few headers such as system.h and hwint.h, with other places testing feature macros defined in system.h (or through autoconf) if it's really necessary to have such dependencies there. -- Joseph S.
