 - I have checked out a clean clone of lily and after running

./autogen.sh
make all
make check

(and importing it into Eclipse which doesn't change anything, lily runs nicely) it gives me this error:

[...]

I'm on Ubuntu 10.04, 64 bit (vmware).

I shouldn't upload my cleaned warnings patch, if regressions don't run on a virgin clone :p.
Any advice is welcome.

Thanks,
