I get a compile failure here on some hosts:

/home/pm215/qemu/blockjob.c: In function =E2=80=98block_job_txn_apply.isra.=
8=E2=80=99:
/home/pm215/qemu/blockjob.c:524:5: error: =E2=80=98rc=E2=80=99 may be used
uninitialized in this function [-Werror=3Dmaybe-uninitialized]
     return rc;
     ^

I guess the compiler can't always figure out whether there is
guaranteed to be at least one thing in the list ?

thanks
