 >>> Ok, thanks... I managed to get it to work using the simple commands:
 >>> $ gcj -c MYLIB.java (creates MYLIB.o)
 >>> $ gcj -shared -o MYLIB.so MYLIB.o (creates the shared object MYLIB.so)
 >>> $ gcj -c MyApplication.java (creates MyApplication.o)
 >>> $ gcj --main=MyApplication MyApplication.o MYLIB.so (links 
MyApplication

Huum! (o:

 >> gcj -shared -o libMYLIB.so MYLIB.o
 >> gcj --main=MyApplication MyApplication.o -L. -lMYLIB
Well, the output seems identical, nevertheless. Though, specifying the 
PIC-option made the stripped version of the shared object smaller. Any 
explanation?

Hey, who said anything about cygwin?! (Although you're right (o:)
But I still get the "MYLIB.so(.text+0x0):crtstuff.c: multiple definition 
of `___do_sjlj_init'" error whether doing it your way or not.
I think I'll just try gcc 3.4, and see if it works there...
