Hi Martin Sebor,
As explained in the C++ Readme
http://developers.sun.com/prodtech/cc/documentation/ss11/mr/READMEs/c++.html#cNameMangling
this is a known problem we cannot fix without breaking existing code.
We have an undocumented compiler option
-Qoption ccfe -abiopt=mangle6
that generates correct mangling. For a a program to link successfully, all parts of it must be compiled with this option. The option is therefore not suitable for middleware or libraries that are distributed widely.
The Readme provides some workarounds.
Regards,
Steve
