Yesterday was national holiday here in Finland and today I was occupied 
with "real" ;-) work. Thus I didn't have time to start patching and 
autoreconfing sources. Anyhow just  I made test that I could made quickly.

Thank you pointing this out.

I made a test using g++ version 3.4.0 and it seems to be so that the 
compiler bug is still there at least on some level:
- on Linux the compilation went OK with the same g++ version (Linux does 
have weak symbols)
- on Solaris I used only native compiler version 5.5 on Solaris8 and 
version 5.3 on Solaris 2.6 (but Solaris does have weak symbols too, so I 
believe the g++ would work just as fine)
- on HPUX 11 I used native aCC compiler, but at first I was using g++ 
3.4.0 there too to compile 3.3.9-test2 and -- if I remember it right -- 
the reason why I turned to aCC was the fact that compilation ended to 
very same error that happened now on HPUX 10.20

Interesting point is that if I download the test case from [1] and 
repeat the compilation as shown there it really shows that particular 
bug has been corrected in 3.4.0, but exists still in 3.3.2 and 3.3.3:

Anyhow I managed to make working DDD version on HPUX 10.20 and using g++ 
3.4.0 by commenting out "#pragma interface" line from ddd/Assoc.h file.
