are used or not. This uses the same mechanism that is used for APR and APR-util. This may not be the correct solution, but it works, and that is what I really care about. This also renames CHARSET_EBCDIC to AP_CHARSET_EBCDIC. This is for namespace correctness, but it also makes the exports script a bit easier. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@87424 13f79535-47bb-0310-9956-ffa450edef68
