Yes and no. At least, as of the latest spec I've got (which admittedly is a very late C99 draft, not the standard itself). _NETBSD_SOURCE and __builtin_alloca are each in reserved-for-any-use namespace, so there are no grounds for citing the standard as basis for any behaviour whatsoever from that. Ignoring that issue - if, say, they were NETBSD_SOURCE and builtin_alloca instead - then I believe you are correct. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
