ddd does not compile with egcs

[hgweigand_(_at_)_wiesbaden_(_dot_)_netsurf_(_dot_)_de (Hans-Guenter Weigand)]

The devel/ddd port does not compile with our new compiler, it complains
about:

ddd.C 743: initialization to 'void *' from 'const char *' discards
qualifiers

and a whole bunch of equal lines. Egcs does seems to do better type
checking, but I could not find the cause of the errors. Any C++ hackers
here?
