Right, but as long as such a beast isn't available, isn't it more
correct to return zero if strcasecmp finds the names equal?  What
situation do you envision where two strings that are equal for
strcasecmp are not equal in a non-Posix locale?

Hmm.. why not?

As the last resort, how about supporting case-insensitive file-name
comparisons only in the C locale?  For that matter, why not using
strcasecmp alone when we run under the C locale?
