There is the installation manual, available in the tarball and on the
web site.

There's no such thing as libstdc.  libstdc++ must be updated, yes; the
C++ ABI has changed, and so has the library, to become much more
standard compliant.

These are results of lack of C++-standard compliance in your code, I
presume.  You can ignore the warnings, but you'll have to address the
errors.

These might be problems in GCC, but they may also be bugs in GDB, the
underlying debugger that DDD and xxgdb are graphical front-ends for.
You didn't mention which version of GDB you're using, but you may want
to report the problem to the GDB mailing list.
