Hmm, certainly it would be nice to avoid these warnings. Most X11 programs, to the best of my knowledge, do not use any functions from the ICE or SM libraries, which are fairly esoteric. But the AC_PATH_XTRA macro has always (at least since 2001 or so) checked for the ICE and SM libraries and added them to $X_PRE_LIBS, so presumably some programs that use Autoconf depend on that behavior, and removing it would break them. In other words, I would like to do something about this (or to ask the upstream Autoconf developers to do so) but I don't see a way to do it without breaking other things.
