Hi,

We develop a middleware that depends on omniORB. Our configure script 
needs to detect the omniORB major version, to support omniORB 3.x as 
well as omniORB 4.x
It is easy to get the installation directory of omniORB, and in this 
installation directory, there is a sub-directory :
   include/omniORB<major version>/

That is how we guess the omniORB major version.
But maybe you need more accurate information ...

Hope this helps nevertheless,
