The problem is between r125620 and r125628 but is NOT, as I
suspected, r125621.
Is nobody else seeing it, or is it a Cygwin specific problem?
ia64-linux testresults with rev. 12640 appear to be fine (http://
gcc.gnu.org/ml/gcc-testresults/2007-06/msg00572.html).
Doh, wait, it appears that rev. 125624 is the dataflow merge.
Although it doesn't appear to touch specific cygwin files, it
certainly is a commit with sufficiently high order-of-magnitude that
it can disrupt a few seemingly unrelated code paths. Maybe it's worth
trying to bracket that one? (although I know cygwin bootstrap is
awfully slow)
