Not true.  But you are correct that in 1.7 it is harder to get text mode
processing in a default install, because text mode is a) slower, and b)
less tested.

Not true.  Cygwin can read windows shortcuts as symlinks, but does not
generate windows shortcuts to hold new symlinks because windows
shortcuts are inherently limited in such a way that they cannot serve as
true POSIX symlinks.

Such a patch will never be accepted in the cygwin port of bash.
