Kaffe crashes on DragonFly/i386 with errors which don't really make any sense and vary from time to time.

This is only one example, made when trying to build wip/jdk15

Kaffe may use different engines to execute java code
  - one interpretor (intr)
  - one just in time compiler among two (jit or jit3)

Its documentation says
  The jit3 just-in-time compiler is used to translate Java byte codes
  into native machine code, resulting in a significant speedup over the
  interpreter.  However, unlike the interpreter, the compiler must be
  ported by hand to new architectures and operating systems.

The default execution engine on DragonFly/i386 systems is jit3. Howewer, it hasn't been adapted to DragonFly and crashes.
On amd64/x86_64 systems, the only available engine is intr, which explains why Kaffe runs fine on DragonFly/x86_64.
>How-To-Repeat:
Try to build wip/jdk15 with kaffe from pkgsrc on DragonFly/i386
>Fix:
Force the choice of execution engine to be intr on DragonFly systems.
Add these lines to lang/kaffe/Makefile to do it:

+.if !empty(MACHINE_PLATFORM:MDragonFly*)
+CONFIGURE_ARGS+=       --with-engine=intrp
+.endif

 Wow, that was fast.

 Kaffe from pkgsrc -head is fine.
 Kaffe-x11 is still building its dependencies. Unconfirmed for now.
