Hmm - I'm using just standard unstable Debian - so you should be able
to see which symbols are present there (unless you do not have libGL installed)
I do not know which symbols shouldn't be exported by libGL - but
dynamic_cast is definitely not in them - moreover it's not present
in any other library linked with avifile except
/usr/lib/libstdc++-libc6.2-2.so.3
As I said I've currently removed the need of this in my avifile project
however my second project is quite based on the proper functionality
of this casting - as it's using it for object identification
(thus saving one member value for typeof)
