State-Changed-Why:
    See libstdc++/6062. I'd appreciate it if you'd try this with the gcc-3.1 toolchain. 
    
    Building with a current toolchain on linux:
    c++ -rdynamic -g -fPIC -Wall -shared mydll.cc -o lib5166.so 
    c++ -rdynamic -g -fPIC -Wall main.cc -L. -l5166 -ldl -o test.exe
    
    Gives:
    
    %./test.exe 
    hello
    hello
    
    
    Thoughts? This is probably what you were expecting on HPUX. 
    
    I think this is either a gcc-on-HPUX specific problem, or a problem with the HPUX dynamic linker. Thoughts on how to proceed?
