>Description:
The rule in Makefile.am used to produce CNI header files
looks like:

nat_headers = $(ordinary_java_source_files:.java=.h)

This means that gcjh only gets run for top level classes
that are represented by a .java file, and not for inner
class files which also may have been generated. This means
that native code can not use inner classes unless the 
required inner class is special-cased in the Makefile.

I see two possible solutions:
1. Modify gcjh to look for inner classes, and include them
in the produced top-level .h file.
2. Modify Makefile.am to find the complete list of 
generated .class files and run gcjh against them.

The first option may be more work to implement, but is
preferable since it is a more general solution and the 
produced CNI interface seems like it would be 
cleaner/easier to use than having to #include a separate 
header for each inner class.

Also, we probibly do not want to produce .h files for 
anonymous classes, and this logic would be better implemented
in gcjh than in the Makefile.
