Boris,
I appreciate your attention & support.
Now I attempted to build xerces library using g++ compiler. I did not
find any instruction for that, but followed the following steps:
export OBJECT_MODE=64
./configure CFLAGS="-maix64" CXXFLAGS="-maix64" LDFLAGS="-maix64"
gmake
Now gmake spews too many ld errors, e.g.
/bin/sh ../libtool --tag=CXX --mode=link g++ -maix64 -D_THREAD_SAFE
-maix64 -o StdInParse src/StdInParse/StdInParse.o
src/StdInParse/StdInParseHandlers.o ../src/libxerces-c.la -lnsl
-lpthreads
g++ -maix64 -D_THREAD_SAFE -maix64 -o StdInParse
src/StdInParse/StdInParse.o src/StdInParse/StdInParseHandlers.o
../src/.libs/libxerces-c.a -lnsl -lpthreads

If you're only getting these duplicate symbol warnings, then it's OK.
The AIX linker is not savvy enough to understand that there will be many
duplicate weak symbols when linking C++ objects, because of inline
functions and template instantiations.
It's been several years since I've worked on AIX, so there may even be a
linker option now to suppress duplicate weak symbols.
