To see if the string represents a negative value and fail; can't do that
with strtoumax alone (or I don't know how to). For example, if I call
strtoumax("-40", NULL, 10), it returns 18446744073709551576 (UINTMAX_MAX
- 39) on my computer and leaves errno unchanged. I don't want that,
perhaps it wasn't clear in OP.

I didn't know this. Not sure how much adoption the current C standard
found but it's definitely a step forward for the language. Good.
