Well, it created a Makefile.in of correct size.

Well, if I glance the Makefile.am a bit more thoroughly, I find that 
there is a list of files - namely "nat_source_files" - containing a 
reference to the file "gnu/java/awt/natEmbeddedWindow.cc".
This file references to e.g. "gnu/java/awt/EmbeddedWindow.h"
I guess this file is created by gcjh from 
"gnu/java/awt/EmbeddedWindow.java" (right?), but this file is no longer 
in my "awt_java_source_files" list. So, I'm not sure it'll work (haven't 
tried it though)?

Well, I don't quite know the parameters for "configure" in order to get 
it to create the Makefile. The reason is that I'm using Crosstool...
Maybe I should start out building for my own x86 target... :o)
