On recent builds of R-devel, R CMD check gives a WARNING when some

That is not the canonical R sources. And your description seems wrong:
there is now an _optional_ check controlled by an environment variable,
primarily for CRAN checks.
Are the canonical R sources made available in such a way that one can
link to them?
Yes, the sources are available. To link to revision 73909 of R on the
trunk branch (which I think is the one referred to above), use
https://svn.r-project.org/R/trunk/?r=73909
I'm not sure if there's an easy way to see the diff between that and
73908 (which is what the github link showed).
After checking a bit online, it appears there are projects WebSVN, USVN
and ViewVC that should do this. I don't know if anyone has set up views
of the R repository with any of those. I've never used them, I just use
local tools. In the past I used Windows-only TortoiseSVN (and it is
still one of the most attractive features of Windows); now I use RStudio
or command line svn. As you know, RStudio's interface is somewhat
limited, and as far as I know it can't display features of remote
repositories.
I also don't know if
there's a way to show the diff between commit N and N-1 in github if I
only know N.
I still don't know this.
