My code is designed to not care how the system locale is set: it explicitly says it will use only the ctype category, and then explicitly sets that category to ISO-8859-1, so that the locale settings of the shell are overruled.

What do you think might be wrong with my setlocale() call? locale -a outputs

C
POSIX
en_US
en_US.iso88591
en_US.utf8

The warning still appears even if I give setlocale() its lowest-common-denominator setting, 'C', instead of 'en_US.iso88591'.
