Hi, since I didn't get any reaction at all, neither in this mailing list nor at the bug report I created at 'savannah', I'd like to resubmit. Paul possibly has seen this problem before, and may even have a patch available; reports of reproducibility from other platforms might also help narrow down where to look. I all doesn't help, I'll have to dig down the code. I know it's not a major issue here, but I need consistent behavior in my makefiles, either way.
