No idea.  The code to create the tmp dir seemed to have been working
up to now.  But you might be right, we'll see that afterward.

to here, it's looking for the tmp dir name, and found it.  Fine.

This is the actual failure.  I don't understand the error msg at all.
I doubt that the tmp dir what not created, I suppose `autoconf' would
have failed, but who knows...

To check that it was created, please run

        ./debug-5.sh
        ../autoconf -A .. -d -v

the verbose messages should refer to the tmp dir it used, and with -d,
it should not be removed.  So you should be able to check if it was
created or not.

Other than that,

Good, the error was caught.  But was it clearly displayed?  I don't
remember...

Hm...  Just a stupid idea...  Could you try:

cat >/tmp/foo <<_m4eof
^m4_
_m4eof

and

cat >>/tmp/bar <<_m4eof
^m4_
_m4eof

?  Thanks!
