Hi Andrew,

Opening your link, I have noticed that the fcheck-references is defined for
arm-elf CPU. Also the arm-elf family is compatible with the processor I am
working with (PXA270). Then I will build a new toolchain for arm-elf based
on gcc 4.1.2 and make new tests.

What do you think?

Best Regards,
David Sayada.

OK, it looks like the toolchain is totally misconfigured.  My guess is
that this version of gcj on ARM doesn't work at all.

You need -fcheck-references in that spec file, and the whole library
needs to be compiled with it.  I have no idea whether gcj 4.1.2 ever
worked on ARM; I'm beginning to think not.

Have a good look at 

http://gcc.gnu.org/svn/gcc/trunk/libjava/configure.host

and make sure that the arm*-linux* sections are correct.

This will help, but I suspect that gcj 4.1.2 will never work properly
on ARM.  You need something much more recent.

Andrew.
