commit 3109546b28b5fc55bf451e62cdb80908cf025ff8

    Avoid an type-punned pointer aliasing pbm
    
    Fix this warning, there is no need to use an intermediate,
    different array pointer.
    network.c: In function 'getIPv6Addr':
    network.c:50: warning: dereferencing type-punned pointer will break strict-aliasing rules
    * src/util/network.c: avoid an intermediary pointer cast
