Install autoconf and automake.

Then
cd <root-of your cvs checkout>
./bootstrap

Which versions of automake/autoconf to use and how to install them
depends on the OS you are using.

The versions being shipped by modern Linuxes probably will suffice
(CVS-HEAD needs autoconf >= 2.61, automake-1.10).

Users of older rpm-based Linuxes can use the rpms to be found on
ftp.rtems.org (for CVS-HEAD you will want the rtems-4.9-* packages).

Users of other OS will have check the versions their vendors might be
shipping or will have have to resort to install from sources (to be
found on any gnu-mirror)
