Package: db3
Severity: normal
Tags: patch

When building 'db3' with gcc-3.4 on amd64 I get the following error:

With the attached patch 'db3' can be compiled using gcc-3.4 on amd64.

The patch removes an occurrence of '-lstdc++' from debian/rules which
causes libstdc++ to be linked in statically. This does not work on amd64 
because libstdc++.a is not compiled with -fPIC and is thus not allowed
to be used to create a shared library. 

The '-lstdc++' should not be necessary at all. It seems that it was 
introduced to fix an old libtool bug which must have been fixed long ago.
