Linking errors with swarm i386 under i486-suse

[Marco Weismueller]

Dear Swarm-Team,

I have installed the source code of swarm-2.1.1.tar.gz after I had problems
with the binaries of the package swarm-2.1.1-1.suse.i386.rpm under a
i486-linux system.

The compilation of the source code went ok, despite linking warnings, which
occured at the end of the swarm code compilation and each time, when compiling
programs. The warnings look like this for the heatbugs example:

-------------------------------------------------------------------------------

Somehow, the dynamical allocation of classes seems not quite proper. Is this a
normal behaviour, which can be suppressed by a linker flag or might that cause
serious problems in further usage of Swarm . The examples in the installation
package run properly, even with these warnings.

What do you think about the linker warnings?
