The c_* modules ARE used, particularly in gettext, in situations where
locales do work and strcasestr honors locales at the expense of extra
processor utilization.  The point of Bruno's modules is that sometimes you
_want_ LC_ALL=C semantics, but without having to change the locale and
restore it afterwards.

However, if we have a platform missing strcasestr, then using c_strcasestr
as the substitute implementation is probably okay, because that platform
would probably be broken in other areas, such as locale support, such that
a locale-aware replacement strcasestr would not be worth the effort.
