But I can confirm the fact:
I think the usual response is: don't put /usr/ucb early in $PATH. It hurts for all kinds of reasons. Listing this fact is much more helpful than listing all the deficiencies of the tools in /usr/ucb, some of which are segfaults with weird inputs or so. Maybe the Autoconf manual should contain: please don't put /usr/ucb nor '.' in $PATH, and if you must, put it as late as possible. Dunno, I don't have a strong opinion on all of this. Cheers, Ralf
