title: mingw32-make only runs the first dependency line
body: <p>My Makefile:</p>
  
  <pre><code>helloworldlib.obj: helloworldlib.cpp
      g++ -Wall -o helloworldlib.obj -c helloworldlib.cpp
  
  helloworld.obj: source.cpp
      g++ -Wall -o helloworld.obj -c source.cpp
  
  helloworld.exe: source.cpp helloworld.obj
      g++ -Wall -o helloworld.exe helloworld.obj helloworldlib.obj
  </code></pre>
  
  <p>I'm not sure what's wrong with this, when I run mingw32-make it only executes the first <code>g++ -Wall -o helloworldlib.obj -c helloworldlib.cpp</code>.
  As far as I know this makefile is syntactically correct, mingw just doesn't seem to be able to find the other lines.</p>
