for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper) and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE. All _VAR_ flavors changes to _DATA to be absolutely clear. Thank you Greg, for the most obvious suggestion. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@86609 13f79535-47bb-0310-9956-ffa450edef68
