Thank you very much, David!
In the meantime I stumbled over <http://wiki.winehq.org/WineOn64bit>,
where in the section "The hard way" they state along the lines:
* 64-Bit Fedora/SuSE: install 64-bit libs into /usr/lib64 and 32-bit
libs into /usr/lib (note: not /usr/lib32),
* 64-Bit Debian: out-of-the-box supports only 64-bit libs which are
copyied to /usr/lib and /usr/lib64 is a symlink to /usr/lib.
Support for 32-bit libs can be either
o set up a 32-bit chroot environment, 32-bit libs and programs
need to be installed into /emul/ia32-linux, or
o like in Ubuntu 32-bit libraries get installed alongside into
/usr/lib32
[It is astounding what setup-combinations there are w.r.t. the different
Linux distros and now with different bitnesses!]
