    On this AIX system, mksignames segfaults.  Running
    dbx shows that it was at line 90:

          rtmax = SIGRTMAX;
          signal_names[rtmax] = "SIGRTMAX";    <====

    Install the C for AIX compiler for Visual Age C 5.0.1
    Put /usr/vac/bin in PATH
    export CC=xlc
    ./configure --without-gnu-malloc

    The kludge I did was to alter line 35 from
        char *signal_names[2 * NSIG];
        char *signal_names[1000];
    That's excessive.  However, you might look at the AIX 4.3
    comment -- the #if is clearly not being taken, or the
    segfaulting assignment would never happen.
    Worrying about "so much unused space" is, I think, out of
    place nowadays -- that's 4K of space -- so maybe the limit
    on signal_names just needs to be bumped up.
