Re: [e-users] error on statically linked programs that use imlib2 static libraries

As is, things will not work when using -static. The loaders are loaded 
dynamically as separate shared objects.

One reason to do this is to avoid loading all libraries used by all 
loaders (libpng, librsvg2, etc., and their dependencies) at application 
startup but defer it until needed.
Another is to isolate applications using imlib2 from the licencing of 
the libraries used by the loaders.
