New issue 2892: Unable to build on windows with multiple versions of visual studio installed
https://bitbucket.org/pypy/pypy/issues/2892/unable-to-build-on-windows-with-multiple

Andrew Lawrence:

I have Visual Studio 2010 and 2017 installed on my machine. pypy detects different versions during different stage of the builds. I am under the impression that Visual Studio 2010 is no longer supported and should not be used by the build environment

The get_externals script correctly detects the 2017 version.

When I perform the translation of pypy with the following command the 2010 version is detected.
C:\pypy\pypy\goal>C:\pypy2\pypy2-v6.0.0-win32\pypy2-v6.0.0-win32\pypy.exe ../../
rpython/bin/rpython --opt=jit

```

```

I have tried to set the version of Visual Studio using the CC environment variable but this does not work due to the pypy rejecting some of the spaces in the name.
