Readline and libiberty compilation warnings with SGI CC

Thanks for your report!  Most of these warnings (included below) are
in the GNU `readline' and `libiberty' packages (which I only include
but do not maintain).  This reply is forwarded to the package
maintainers <address@hidden>, who will check whether the
warnings below indicate problems in the package code.

The remaining warnings (not listed here) are in the `cxxtest' demo
program, which is not a part of DDD itself, but of course, a part of
the DDD distribution.  I will try to fix them for DDD 3.3.

Oh, and finally: None of these warnings seems important to me.  But
thanks anyway!
