title: Differences between Mingw-w64 and TDM-GCC for a simple GDI project
body: <p>I need to build a simple non-commercial tool (dealing with Windows GDI API) on Win64 for Win64  (no cross compilation). MinGW seems the best option for me.<br>
  I have already used the 32 bit version in the past, as for 64-bit, can you tell me the main differences between the following builds?:</p>
  
  <ol>
  <li><a href="http://mingw-w64.sourceforge.net" rel="noreferrer">Mingw-w64</a></li>
  <li><a href="http://tdm-gcc.tdragon.net" rel="noreferrer">TDM-GCC</a></li>
  </ol>
  
  <p>Besides the classic MinGW32 used a straightforward tool, <code>mingw-get.exe</code>, to customise the setup and keep up with the updating cycle. Which is the equivalent now? </p>
