# Background: the langinfo() (in C known as nl_langinfo()) interface
# is supposed to be a portable way to fetch various language/country
# (locale) dependent constants like "the first day of the week" or
# "the decimal separator".  Give a portable (numeric) constant,
# get back a language-specific string.  That's a comforting fantasy.
# Now tune in for blunt reality: vendors seem to have implemented for
# those constants whatever they felt like implementing.  The UNIX
# standard says that one should have the RADIXCHAR constant for the
# decimal separator.  Not so for many Linux and BSD implementations.
# One should have the CODESET constant for returning the current
# codeset (say, ISO 8859-1).  Not so.  So let's give up any real
# testing (leave the old testing code here for old times' sake,
# though.) --jhi
