I read this as saying that if _none_ of LANG, LC_MESSAGES, or LC_ALL is 
set, then libintl is smart enough to choose the system default language. 
  But I still think that if LANG is explicitly C.UTF-8, then the user 
_has_ made an explicit language request - namely, the same language as 
for LANG=C (which is more or less English, but not always identical to 
en_US.UTF-8).

How is it POSIX compliant to ignore $LANG by using a different language 
for the C locale?  C.UTF-8 is just the C locale with a different 
charset, not carte-blanche to use the system-default language.
