The GCC 3.2.2 target default is:-
target=i586-pc-msdosdjgpp

>How can I rebuild libstdxx.a?
If you download the GCC322S.ZIP and follw the directions in the
readme.djgpp file in the gnu\gcc-3.22 directory.

In the gcc\buiild.gcc directory modify the djmake.sh to change the
target to the following before you do any builds:-
target=i386-pc-msdosdjgpp

You may also need to re-build the binutils as well, but I would start
with GCC first and see what happens. This should take about 70-90
minutes on a P4 2Ghz and about 3-4 hours or more on a Celleron 800.

If you need any help with this then send me an email and I will try to
help out as much as I can. 

Here is a complex batch file that I used to build and install the GCC
3.2.2 compiler. This is setup for rebuilding so it does a very
thorough job of cleaning the directories which may not be required for
your build:-
