commit 279805b20b9bbd1f73c50bf9e81dffb254f99fe8
Author: Corinna Vinschen <corinna-cygwin@cygwin.com>
Date:   Wed Jul 24 22:32:18 2019 +0200

    hash functions: use reentrant stat functions
    
    _stat64 and _fstat64 are not exported from Cygwin.  Use the
    reentrant analogues, like everywhere else.
