The most common way to do it is to process the file with configure/ 
config.status to make any useful substitutions.

You don't use that information when linking with the library, typically.

The version numbers you see in that example are not libtool library  
version numbers; rather, they are simply part of the library name.

Giving your library a different name on every platform is a bit  
unusual; but you should be able to accomplish it with configure  
substitutions.
