I can reproduce on MacOS X 10.8.5. It doesn't seem to like the
assignment inside the let statement. Possible an issue with the older
bash (3.2) Apple ships?
The attached patch resolves the issue, and I believe does the same
thing. Martin, does this look correct to you?

Subject: [PATCH] Use arithmetic compound syntax instead of 'let'.
Fixes a synax error with 'make check' on MacOS X.
I also fixed the eccentric indent.
