Even doing that left a directory:
> $ find /local/tmp/a*
> /local/tmp/arRdqYXc
so now I know the problem:
mktmpdir is creating *TWO* directories. e.g. /local/tmp/arRdqYXc and
/local/tmp/ar8810.11683 and $tmp is set to the latter. This second
directory is properly removed (if it is empty) at the end of the Perl
run. The former is not. If these autoheader/autom4te "former" temp
directories are left in the autoreconf temp directory, you have a
problem.
So, the question boils down to how come two directories are created
and what can I do about it? :)
