Updated GNU tools

[ableasby at hgmp.mrc.ac.uk]

Dear developers,

With the release of EMBOSS 2.6.0 the CVS master repository has been
updated to reflect the latest GNU tools, namely autoconf, automake,
libtool.  This sort of change is often transparent. Not this time.

People who just use the standard distribution are not affected but
developers may need to upgrade these tools to the latest versions.
They are:

    autoconf  2.57
    automake  1.7.2
    libtool   1.4.3

You can display your current versions using
    autoconf --version
    automake --version
    libtool  --version

You can get them from ftp.gnu.org in the pub/gnu/autoconf [and automake
and libtool] directories. It is OK to install them over the top of
existing versions for most OSs although I'd not recommend doing
so with MacOSX. For example, in RedHat Linux you just need to:
   ./configure --prefix=/usr
   make install

The prefix will depend on both you and your installation. You must
install autoconf first.
