title: GNU make drops target in implicit rule?
body: <p>If I run the following makefile under GNU Make 3.81 / RHEL5:</p>
  
  <pre><code>all: A1B/C A1B/D A2B/C A2B/D
  
  A%B/C A%B/D: E.%
          @echo "Creating '$@' from '$^' with stem '$*'"
  
  E.1 E.2:
          @echo "Generate '$@'"
  </code></pre>
  
  <p>I get the following output:</p>
  
  <pre><code>Generate 'E.1'
  Creating 'A1B/C' from 'E.1' with stem '1'
  Generate 'E.2'
  Creating 'A2B/C' from 'E.2' with stem '2'
  </code></pre>
  
  <p>Why are files A1B/D and A2B/D not generated?
  (files with such names do not exist in my testcase)</p>
  
  <p>If I specify the targets via the command line make states "Nothing to be done":</p>
  
  <pre><code>make A1B/C A1B/D A2B/C A2B/D
  Generate 'E.1'
  Creating 'A1B/C' from 'E.1' with stem '1'
  make: Nothing to be done for `A1B/D'.
  Generate 'E.2'
  Creating 'A2B/C' from 'E.2' with stem '2'
  make: Nothing to be done for `A2B/D'.
  </code></pre>
  
  <p>If I duplicate the implicit rule into their targets it works:</p>
  
  <pre><code>all: A1B/C A1B/D A2B/C A2B/D
  
  A%B/C: E.%
          @echo "Creating '$@' from '$^' with stem '$*'"
  
  A%B/D: E.%
          @echo "Creating '$@' from '$^' with stem '$*'"
  
  E.1 E.2:
          @echo "Generate '$@'"
  Generate 'E.1'
  Creating 'A1B/C' from 'E.1' with stem '1'
  Creating 'A1B/D' from 'E.1' with stem '1'
  Generate 'E.2'
  Creating 'A2B/C' from 'E.2' with stem '2'
  Creating 'A2B/D' from 'E.2' with stem '2'
  </code></pre>
  
  <p>According to the documentation this should not make a difference.</p>
  
  <p>Thanks in advance.</p>
