We treat GitHub as a development repository, just like R-Forge before it.  

To us, it is not a means for general distribution (though we strive to keep
the master branch sane at all times).  OTOH releases are rigorously tested on
win-builder and other platforms. So if in doubt, use CRAN.

That said, even GitHub gets continuous integration and builds on every
commit. Things generally work for the OS X and Linux crowds (for several
flavours of each). We do turn vignettes off on GitHub to save some processing
time. Building vignettes requires highlight (the package) and a decent LaTeX.

As nobody in Rcpp Core develops (primarily) on Windows, if something breaks
you get to keep the pieces -- at least until you, or someone else, fixes it.
