The pattern rule for building %.dvi inserted by
http://gcc.gnu.org/ml/gcc-patches/2003-08/msg01939.html
breaks make dvi (GNU make 3.80): make tries to build objc.dvi
using the pattern rule from objc.texi (the pattern rule being used
as documented because the non-pattern dummy rule has no commands)
which fails as objc.texi is a chapter rather than a standalone manual.
