We probably shouldn't be using strtod/strtold in the first place
because of issues like this, but I think your patch is likely the
simplest fix.

It _might_ be a good idea to limit it to LC_NUMERIC instead of LC_ALL,
but who knows.. I'm not sure what else might be affected (and I'm not
sure how good LC_NUMERIC support is on all platforms)
