gcj/gdb in cross env

I build gcc/gcj 4.1.0 in cross env for target powerpc-linux, and did the same for gdb 6.4.

As I have a "Segmentation fault" with an HelloWorld program written
in Java, and compiled with powerpc-linux-gcj -g, I tried to launch
powerpc-linux-gdb on the exec file, but an error occurred :

Dwarf Error : wrong version in compilation unit header (is 99, should be 2) [in module HelloWorld]

What I did :

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".

Thanks for your help.
