Host
 powerpc-linux-gcj -g -o HW HW.java --main=HW --static
Target
 gdbserver host:2345 HW
Host
 powerpc-linux-gdb HW
 -> Dwarf Error ...
 under gdb : target remote vmpc:2345
 but after, no debug is possible (no symbol table, no stack, etc)
When I built gdb 6.4 for target powerpc-linux, I have to configure it with --disable-werror, because without that, the build stopped due to several warnings of "value computed is not used".
