I know, but regular support has ended in March 2009 alreay, this one is
only by special arrangement.  E.g., Solaris 8 patches are only available
anymore with a special contract.

I'll probably do so soon so people get a heads-up.

Not really: this is a stupid bug in a documented feature and supposed to
work.  A fix shouldn't be hard, but probably after 4.6.0 is released.

That's part your fault and part ours: while install.texi states `MPC
Library version 0.8.1 (or later)', later versions are rarely tested and
often break, so it's best to stay with those exact versions.  We need to
improve the install docs in this regard.

I'm reluctant to document every corner case in install.texi: nobody will
read this and important stuff gets missed.  This PR will probably have
to do.
