Chuck, The wrapper scripts for autoconf and autoheader use temporary files that they (are supposed to) remove on exit (using trap 0). But I tend to find *lots* of these directories in /tmp (e.g. /tmp/acXXXXX and /tmp/ahXXXXX). Just running autoconf or autoheader with no arguments creates a nice example.
But I can't see what the problem is with the scripts: they set a trap to clean up and it looks fine to me. Any suggestions? // Conrad
