User defined categories in the locale definition file were not supported. That is, categories that are not LC_CTYPE, LC_COLLATE, LC_MONETARY, LC_NUMERIC, LC_TIME, LC_MESSAGES, LC_SYNTAX or LC_TOD were not processed by the localedef utility.
The locale has not been created. If BLDERR option is specified, the unsupported categories are ignored.
Remove the unrecognized category from the locale definition file.
