I'm guessing you're talking about Windows, which has different and 
incompatible builds of debug and release libraries. Actually, that applies 
only to Visual Studio -- the MinGW DLLs are compatible with each other.

But your question does not make sense. The linking time applies only to your 
own code. If you're debugging, you need to build your own code in debug mode 
and since the linking time is proportional to the size of your own codebase, 
it'll be as slow as it needs to be.
