Hmm... this doesn't sound very familiar to me, but it just might be related
to other problems when building with gcc newer than 2.95.

In the Debian GNU/Linux package of DDD, I needed to apply the following
changes in order to get DDD built on architectures that use gcc 3 as their
default gcc version:
  * ddd/logplayer.C: include system header <fstream.h> before local
    includes.
  * ddd/rxscan.C: disabled declaration of isatty that's broken for g++ 3.0.
  * ddd/strclass.C: fixed type of new_state from int to ios::iostate so it
    works with g++ 3.0.

Can you try if applying the following patch makes a difference?

If the patch doesn't make a difference, your best bet is to do a binary
search for the offending line in the initialisation gcc complains about
using #if 0 ... #endif blocks and then report back to this list which line
is problematic.
