I'm not sure how easy this will be to reproduce without mingw (maybe you can see it if someone provides the preprocessed source?). In the meantime, would you mind reverting to see if this failure goes away?

Reverted in r127909.  Joerg Sonnenberger sent me preprocessed source
already; I'll look into it soon.
