 `r.viewshed`, `r.terraflow` and `i.atcorr` are not working in the new MS
 Windows builds. These are C++ modules and does not work in 32bit and 64bit
 versions.

 The executable exists. The error message when running r.viewshed from the
 system terminal is shown in a dialog:

 {{{
 The application was unable to start correctly (0xc000007b)
 }}}

 In relation to this message a [http://stackoverflow.com/questions/10492037
