The build system has grown rather organically along with the rest of the 
project. While my contributions to it hardly constitute a major part of 
the system, they have been non-trivial, and my understanding at the time 
was that the build system, like the code it accompanied, was intended to 
be released under the Vovida license.

Those directories are (to my knowledge) used only by the Windows (Visual 
Studio and MinGW, not Cygwin) builds. They need to remain in the project 
tree, but can be omitted from any non-Windows packaging.
