Sorry, I don't see how this will work either.
It's common for a GMP-less expr to handle values
only up to SIZE_MAX / 2, and subtracting just 1
won't work around that problem.

Maybe divide by 10 instead?  That's easy to do
textually.  (I don't know what the test is about
so I'm not sure what to suggest.)
