Thanks to all for your responses. As pointed out by a few of you, using
expr is indeed safer, and is what we ended up using in our script to get
it accepted in CRAN.

This was exactly my point, and I think it would be great to have this
clarified in the manual to avoid any unsuspected surprises during
package submission. Since R expectations are naturally aligned with
autoconf's it would be worth noting that, and maybe also pointing to the
resource pointed at by Iñaki.
I think the discussion about supported OSs is also an interesting one,
but is greater than just about this particular subject.
