title: f2py fails to run - error in CompaqVisualFCompiler, with no compaq compiler installed
body: <p>I'm trying to use f2py (under anaconda 2, windows 7 64bit, python 2.7.13) but I run into the following error repeatedly, even when simply trying to list available compilers:</p>

  <p>I've installed minGW for anaconda (via <code>conda install mingw</code>), so it <em>should</em> detect and run that. I'm not too sure but it seems like it's trying to find the compaq one instead and failing at that? Here's the relevant section of compaq.py (line 100 is the final line):</p>
