cxa_atexit with gcc3.2.3 on solaris2.6

[Juan Carlos Franzoy <jfranzoy@xxxxxxxxxxxx>]

Hello.
I am having a problem compiling gcc3.2.3 on solaris2.6.  I run configure this way:

mkdir gcc-objdir
cd gcc-objdir
../gcc-3.2.3/configure --prefix=/usr/local/gcc-3.2.3 --enable-shared --enable-threads=posix --enable-__cxa_atexit --with-as=/usr/ccs/bin/as  --with-ld=/usr/ccs/bin/ld --enable-languages=c++

The linker says that __cxa_atexit is not defined !!

If I do not use --enable-__cxa_atexit I could not do dlopen of a dynamic library with static objects. The samples are attached. These samples are not mine. To compile them I run:

g++ -shared libtest.so -fPIC test2.c
g++ -oprueba test.c

The output of 'prueba' is:
In main
In shared object
Shared object creating ...
Back in main
Goodbye, world.
Segmentation Fault(coredump)

What I could read in the Net is that the destructor of the static object inside g() is called after dlclose. Has anybody there know a solution for this?
Thanks.
