title: MinGW make: copy: command not found
body: <p>I'm trying to compile hp2xx on Windows 10 using MinGW. My makefile is a straight copy of the dosdjgpp.mak file from the makes directory. I have c:\MinGW\bin and C:\MinGW\msys\1.0\bin in the path.</p>
  
  <p>The make operation fails at the first copy. The makefile line it is failing on is </p>
  
  <pre><code>pbuf.o: picbuf.o
      copy picbuf.o pbuf.o
  </code></pre>
  
  <p>and the error is</p>
  
  <pre><code>copy picbuf.o pbuf.o
  make: copy: Command not found
  make: *** [pbuf.o] Error 127
  </code></pre>
  
  <p>From the same command prompt I can use copy OK, so why can't make find it?</p>
