#include <unistd.h>
#include <apr_portable.h>

    apr_file_t *file = NULL; /* ### grumble. NULL needed... */
    status = apr_put_os_file(&file, STDOUT_FILENO, pool);
    return file;

The put_os thing is os-specific, so it isn't portable.

[ and no, don't ask me why apr_portable is the non-portable crap. ]
