There isn't a standard test for detecting whether or not -mieee is available (at least, none that I know of). The only workarounds that I've found were when someone used the host detection bits and conditionalised on them. As for what ARCH should be...probably "alpha*-*-linux-*" would be best (since alpha* is too generic and Tru64 would be impacted). C
