Someone on the SuSE list posted some problems she was having with
Oracle. The problem tends to be not so much with C objects but with C++.
The 4.0 compiler uses libstdc++.so.6.xxx where the 3.4 uses
libstdc++.so.5.xxx

Supposedly, the C++ ABI is supposed to be stable. 

In the enterprise arena, generally, 3rd party software is generally
certified for a specific platform/release, such as Red Hat Enterprise
Linux 4.
