/*
* If ENOENT || ENOTDIR is not defined in one of the your OS's
* include files, APR cannot report a good reason why the stat()
* of the file failed; there are cases where it can fail even though
* the file exists. This opens holes in Apache, for example, because
* it becomes possible for someone to get a directory listing of a
* directory even though there is an index (eg. index.html) file in
* it. If you do not have a problem with this, delete the above
* #error lines and start the compile again. If you need to do this,
* please submit a bug report to http://www.apache.org/bug_report.html
* letting us know that you needed to do this. Please be sure to
* include the operating system you are using.
