There are only 5 exceptions at present (KernSmooth, bqtl, fracdiff, gss,
quadprog and quantreg) that need rebuilding.

This should be much easier come R 1.5.0, when all that needs to be done is
to replace a single DLL, and then we can make various versions of that DLL
available.  For those who are interested, it might be better to use the
current R-devel, which is already set up for this.

No, it's not.  People have enough problems doing it manually!
