I realized that there was a different point tacked on here that has not been answered:

By the way, I noticed that -make all recommended- still builds the CHM
help files for certain packages (e.g. Matrix) even though I set
USE_CHM=FALSE in MkRules. Is this expected?

Yes, it was expected. MkRules is only used for building R, not installing packages. The default for installing contributed packages is to build CHM help if and only if the Help Compiler is available, so all recommended packages followed that rule.

We haven't made a final decision yet whether to support CHM help in future versions (and one point R-devel did not do so and it was planned to drop this for 2.9.0): my expectations are that we will support it in 2.9.0 and that USE_CHM will then control the options used to install the recommended packages, but that support may be withdrawn at some not too distant point.

I intend in the next week or so (GFF is Mar 20) to review what loose ends there are in package installation and Windows builds and tidy them up. Once we have an alpha pre-release, reports on such matters will be welcome but until then they are a distraction.
