I haven't tested, partly because it is such a new feature of cygwin, and
there are so few existing programs that even try to expose st_birthtime to
the user.  MSDOS (meaning FAT) actually DOES record birthtime (it only
records birthtime, mtime, and atime, and lacks POSIX ctime; but outside of
cygwin, Microsoft mistakenly treats birthtime as their ctime in stat).
And part of the joy of it being a CVS development snapshot is that I can
give some feedback back to the cygwin developers - what would you rather
have stat do when btime is not available for a given file?
