Ok, sorry Andrew (and Richard), I figured out what is going wrong and is
unrelated to your patches: I have now installed coreutils 5.2.1 and the
use of 'head' which we are making here, in acinclude.m4:

  # Start by getting the version number.  I think the libtool test already
  # does some of this, but throws away the result.
  changequote(,)
  ldver=`$LD --version 2>/dev/null | head -1 | \
         sed -e 's/GNU ld version \([0-9.][0-9.]*\).*/\1/'`

triggers an error:

head: `-1' option is obsolete; use `-n 1'
Try `head --help' for more information.

I think the issue is known, but I don't remember the outcome... Someone
remembers?

Paolo.
