    Bug 12753: Zeroing timestamps in PE headers.
    
    Switching to a new toolchain for Windows (using Binutils 2.24 and
    GCC 4.8.3) led to new problems producing Windows bundles in a reliable
    fashion. Thanks to a patch by a cypherpunk we avoid differences in
    PE header timestamps as one possible source for the issues mentioned
    in bug 12753.
