I'm surprised the problem ever went away, as the subtle quoting differences between cat <<EOF $text EOF and echo "$text" make it difficult to replace the former with the latter. I have Autoconf 2.59 installed, and just did the following with the autoconf 2.57 source code. cp -pr autoconf-2.57 autoconf-2.57-built-with-2.59 (cd autoconf-2.57-built-with-2.59 && autoconf) diff -pru autoconf-2.57/configure autoconf-2.57-built-with-2.59/configure and didn't see a single change on any line that contained '<<'. For what it's worth (which is not much), autoconf-2.57/configure and autoconf-2.57-built-with-2.59/configure ran at the same speed on my Debian 3.0r1 box. So I don't know what the problem is. Unless someone else pipes up with the real answer then I suppose we'll have to get to the bottom of this ourselves. If you have access to an old host, perhaps you can do the same thing as the above, and run "sh -x configure" in both directories, and compare the results to see why one is generating many more temporary files than the other.
