According to Apple's documentation, .jnilibs can be either bundles or 
dylibs:

http://developer.apple.com/documentation/Java/Conceptual/Java14Development/05-CoreJavaAPIs/CoreJavaAPIs.html

"In building your JNI libraries, you have two options. You can either 
build them as bundles or as dynamic shared libraries (sometimes called 
dylibs). If you are concerned about maintaining backward compatibility 
with Mac OS X version 10.0, you should build them as a bundle; otherwise 
you probably want to build them as a dylib. Dylibs have the added value 
of being able to be prebound, which speeds up the launch time of your 
application. They are also easier to build if you have multiple 
libraries to link together."

I'm guessing it ought to be possible to support bundle-style jnilibs in 
libgcj, anyway, possibly jumping through some additional hoops in 
libgcj's loadLibrary implementation. In any case, that is something to 
worry about after the header issue is addressed ;-)
