commit a88ddc902b804a6156f6e5e5feb979754a3e789a
Author: Peter TB Brett <peter@peter-b.co.uk>

    Use statvfs64() for pathconf(_PC_NAME_MAX).
    
    pathconf(_PC_NAME_MAX) was implemented on top of statfs().  The 32bit
    version therefore fails EOVERFLOW if the filesystem blockcount is
    sufficiently large.
    
    Most pathconf() queries use statvfs64(), which avoids this issue.  This
    patch modifies pathconf(_PC_NAME_MAX) to do likewise.
