Sorry for the huge delay in replying - this was buried in my e-mail and I
didn't spend time looking at this. Gary Thomas here just did, and it looks
like you have found an inconsistency in the way gcc handles its arguments.
As a workaround, can you try also using "-G 0" as well as (or possibly even
instead of) -msdata=none? I haven't tried it but it may fix your problem for
now.
