four patches

[Stepan Kasal]

Hello,

I created the following four independent patches:

autoconf-20050629-ccc.patch
autoconf-20050629-precious.patch
autoconf-20050629-canon.patch
autoconf-20050629-subst-files.patch

autoconf-20050629-ccc.patch  eliminates the unintentional AC_SUBST(CCC)
        which I introduced some time ago

autoconf-20050629-precious.patch  changes the way precious variables are
        handled.  (Though its function doesn't depend on the previous patch,
        it won't apply smoothly without it.)

The remaining two are decribed sufficiently by their changelog entries.

Paul and others, do you see any problems before I commit?
