| ## New `vs2012` and `vs2013` backend options |
| |
| Adds the ability to generate Visual Studio 2012 and 2013 projects. This is an |
| extension to the existing Visual Studio 2010 projects so that it is no longer |
| required to manually upgrade the generated Visual Studio 2010 projects. |
| |
| Generating Visual Studio 2010 projects has also been fixed since its developer |
| command prompt does not provide a `%VisualStudioVersion%` envvar. |
| |
| ## Developer environment |
| |
| Expand the support for the `link_whole:` project option for pre-Visual Studio 2015 |
| Update 2, where previously Visual Studio 2015 Update 2 or later was required for |
| this, for the Ninja backend as well as the vs2010 (as well as the newly-added |
| vs2012 and vs2013 backends). |
