linking a .so with libgcj.a ?

Yes, stripping libgcj.so.5.0.0 works wonders. It's down to 9Mb here.
While this works fine on Linux, it doesn't work on Mac OS X. I stripped
libgcj.5.dylib, the .so is made but upon loading it I get a dyld failure on a
bunch of libgcj symbols such as __Jv_InitClass, __Jv_AllocObject, etc.. (about
a dozen). On Mac OS X, a python extension is linked as a bundle.
As for the GDB stack trace, I didn't get any with my default flags, I'm
building for debugging now, but the GDB stacktrace was ominously short (2
lines of ???).
