[omniORB] clang compiler warning in omniidl generated code

[Peter Klotz]

Hi

After a recent switch to clang we started getting this warning:

--------------------
IdlTypes.cpp:13:20: warning: unused variable '_0RL_library_version' [-Wunused-variable]
static const char* _0RL_library_version = omniORB_4_2;
                   ^
1 warning generated.
--------------------

A simple omniidl patch silenced the warning but the question came up what the variable is for.
The code seems fine without. It is not referenced or checked anywhere.
What purpose does it serve?

Regards, Peter.
