Re: How can I get rid of dinkleberry autotools temp dirs?

As is typical, I press "send" and suddenly something dawns on me:

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?  :)
