This is the exact same problem documented earlier in this thread, and yes, 
coreutils-6.9-1 will fix it (I'm getting closer; I've finally completed my 
testing of my ln enhancements, but still need to test my postinstall script).

Try ls -l --append-exe /foo, to see the truth - rather than creating "/foo", 
the broken .exe magic in ln 6.7 created "/foo.exe", but then the auto-exe magic 
in other commands (such as ls) means that 'ls foo' succeeds even if it had to 
do 'ls foo.exe' under the hood.

rm intentionally doesn't do .exe magic.  Last time I tried to do that, it broke 
libtool.

Which is why I'm changing 6.9 to not stick implicit .exe on the end of symlinks.
