Yes.

Wrong.

'BH' is called 'BH', believe it or not, to save a few letters, or else I
would have a dozen or more files complain for the very same reason (and CRAN
reject it for non-suitable path/filenames).  Hence not 'BoostHeaders' but
just 'BH'. And see the ChangeLog of BH and revel in how _each_ release has to
rename one of the Runge-Kutta integration files to make the 'net' path length
be suitable for R packing.

There is no point in ignoring the output of R CMD check unless you _really_
know better.
