    Thomas> Uwe, if I recall correctly you added these lines (correct me if

Hello,

I run on Opensuse 11.4 with x86_64. Packages for my system have and need the
x86_64 extension. Compiling a package without above construct results in a
rpm package without the x86_64 extension. So witout other changes, I still
need the lines above...

Bye
