Дополнительные константы макросов, имена которых начинаются с LC_ следуют по крайней мере одной заглавной буквы, могут быть определены в <clocale>. Например, спецификация POSIX требует LC_MESSAGES и GNU C библиотека определяет дополнительно LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT, и LC_IDENTIFICATION.

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.
