    Thanks, That did the trick. I figured it was something like that
    but did not have time to dig into it myself. As I said, the newer
    compilers seem to be more picky about this kind of thing. I had
    several of my own programs that compiled perfectly with the old
    compiler.. that started breaking with the newer ones .. because of
    duplicate #include .. or in at least one case, changing the order
    of the #include fixed it.

    Now.. I need to get the front-ends to make.. Last I checked the
    ./configure was complaining about something. I hope to get back
    to it this weekend.
