Nothing is initialized until used. If you don't use FLAC it never
tries to load the DLL. This is obviously an *improvement* over
standard linking. Allegro currently has to get around that annoyance
by putting everything in its own DLL. (allegro_flac).

The only down side to my proposal, that I can see, is that if you
*choose* to create a monolithic library with standard "build time"
links, you'll have to distribute every codec DLL. But, in my opinion,
that's just a contrived case that nobody seriously would ever want to
do.

Basically yes, except "crap load" is only ~10 per module. And it's
done conditionally... if the library wasn't found at compile time.

It's all in the diff, do a search for "libdumb_dll" in particular.
