Nice.

That could a bug of my making.  Look at the sources -- on Unix / OS X we run
the (standard script configure) which moves RcppArmadilloLapack.h.in to
RcppArmadilloLapack.h and adjust one setting (based on which BLAS / LAPACK
libraries are used; this is due to a change from last fall).  I am wondering
if I overlooked something for Windows here...

Could so a simple check with a smaller package without any of the other added
complexities (maybe even via RcppArmadillo.package.skeleton()) and see if
that works?   If it does, try adding the other pieces one by one and see
where it breaks.

It may well be a little unlikely that I broke all Windows builds or I would
have heard from Uwe, but it still seems somewhat probably that this is related.
