Probably I have not been paying enough attention to this topic stream 
and I might be misinterpreting the above.  While it is nice to dream 
about not having the .la files, the module loading can not work 
completely reliably without it.  A program may depend on preopened 
modules, dynamically loaded modules, and dynamically loaded DLLs which 
are loaded as dependencies.  The .la files contain the dependency 
chain information.  Using them allows a dependency library to be 
changed without breaking things.
