   7  * ap_log_error does not support %zd or %zu conversion for type_t arguments
   8  * So with ap_log_error one would have to specify either %d or %ld, depending on the
   9  * platform (32-bit or 64-bit). This violates the whole purpose of type_t, which
  10  * was introduced in C exactly to provide cross-platform compatibility...
  11  * This wrapper function supports %zd and %zu conversion parameters.
  12  * Note that it truncates the logged message to 1000 bytes, so don't use it to log messages that might
  13  * be longer
