Original:
Additional macro constants, with names that begin with LC_ followed by at least one uppercase letter, may be defined in <clocale>. For example, the POSIX specification requires LC_MESSAGES and the GNU C library additionally defines LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT, and LC_IDENTIFICATION.
