title: cygwin 64 bit - can't install Pillow via pip
body: <p>I can't seem to install pip on cygwin 64-bit no matter which of the gcc compilers i install. i've tried all of the ones that come up when is search for g++</p>
  
  <p>does anyone know which one i should use? or if i'm going about this completely the wrong way?</p>
  
  <p>when building pip i get errors like this:</p>
