  * Stopped at 132243.
  * Discussed Avinal's request to close bugs that are invalid or get review before closing bugs.
   * Carlos: Close bugs that are obviously invalid, and post to libc-alpha@sourceware.org for review of other issues. Raise those issues on this call and we can find a reviewer.
   * Carlos: I'll review your request about bug 14362.
  * Adhemerval: Did Wilco get a chance to look at SHARED-FILES for Arm routines?
   * Wilco: Not yet.
   * Adhemerval: I'll send a new version with just SHARED-FILES changes.
