The GraphicsMagick (http://www.graphicsmagick.org/) snapshot versions 
are using a non-recursive build with sources in subdirectories. 
Libltdl sources are used directly (without a convenience library). 
Except for libtool bugs, it is working fine.  Given the existing 
libtool bugs (attempts to write to a non-existent .libs directory), it 
would be best to put all the built libraries in the top directory. 
Using sources and objects in subdirectories (Automake responsibility) 
works fine though.
