Bug 35584316

On Oracle Linux 9 or Red Hat Enterprise Linux 9, C++ applications built with g++11 cannot be used with Oracle C++ Call Interface (OCCI).

Workaround:

If the application uses c++11, then link the application with $ORACLE_HOME/lib/libocci_gcc53.so.21.1 instead of the default libocci.so.21.1 and use the compilation option:
```
-Wno-narrowing
```
If the application uses the default libocci.so.21.1, then use the following compilation options:
```
-D_GLIBCXX_USE_CXX11_ABI=0 -Wno-narrowing
```
