I still think that a backwards-incompatible change to something as central 
as linking semantics (the implicit linking is more or less part of ELF 
semantics) hitting so many packages is a very bad idea and that it's 
unrealistic to get them all fixed for F13.

I also think that this change will probably force us to ship .la files. The 
only reason we didn't need them so far was that implicit linking feature.

Sadly, my concerns got ignored at the FESCo meeting where this "feature" was 
discussed:-(
