commit 8df79c9fa79b6ce86fec0342f779125c85ff2f12
Author: Jim Meyering <address@hidden>
Date:   Sun Jan 20 22:19:54 2019 -0800

    build: ensure no VLA is used
    
    Cause developer builds to fail for any use of a VLA.
    VLAs (variable length arrays) limit portability.
    * configure.ac (nw): Remove -Wvla from the list of disabled warnings,
    thus enabling the warning when configured with --enable-gcc-warnings.
    (GNULIB_NO_VLA) Define, disabling use of VLAs in gnulib.  This commit
    is functionally equivalent to coreutils' v8.30-44-gd26dece5d.
