Hello Kristian,

Very cool!  Thanks for your continued work in this area.  Hopefuly we
can get a *convenient* Android build from all this.

But it's not a true cross-compiler, is it?  As I understood it, the
Android Makefile from Bevuta just cross-compiles CHICKEN itself, 
completely, rather than providing a working csc on the host platform
which generates executables for the target platform.

I was hoping someone would do something like that.  It's the natural
next step, and would simplify building for all these stupid different
supported architectures.

Have you considered simply filing a bugreport for the Android NDK?
I think the requirement that all .so files must be prefixed with 'lib'
is pretty bogus.  Hopefully if they do fix it this will be on the NDK
side, and it could be used even for older devices.

Thanks again!
