Which comes with its own portability headaches :)

It's also awkward that we have strerror_l() but not printf_l() for 
getting localized %m output - but then again, printf_l() would be useful 
even without %m for getting the right radix character and thousands 
separators.

At any rate, I'll go ahead and patch the docs to mention %m.
