If *FILE is a target, then the file must be mentioned in the
makefile also as a target to be chosen.
The restriction that *FILE must not be a target for a
makefile-mentioned file to be chosen was added by an
inadequately commented change in July 1990; I am not sure off
hand what problem it fixes.
In December 1993 I loosened of this restriction to allow a file
to be chosen if it is mentioned as a target in a makefile. This
seem logical. */
