No, I'm saying that other windows ports of GNU tools most likely
(mis)use ctime as birthtime, whereas cygwin properly uses ctime as ctime
and exposes birthtime separately.  Since the BLODA is affecting ctime,
but only cygwin is exposing ctime, then only cygwin is likely to be
affected by this patch.
