Not sure I understand which comment you alluded to and how it answers
my questions, so let me ask directly: are you saying that some systems
don't support 'setlocale' with second argument anything other than "C"
or the empty string, but do support changing the locale when
'setlocale' is called with empty string as the second argument and the
actual locale is specified in the environment?
