setup/symlinks/gcc/chown question

Hi All...

It appears to be file permissions related. The link being broken looks like 
it is because the read only bit on the shortcut file (the .lnk file) is 
getting turned off. Even though this first getfacl shows write access, the 
read only box in the windows properties is checked. after the chown -h the 
windows properties box says not a valid link. After the chmod -R 755, the 
windows properties shows it as a valid shortcut, but the read only box is 
unchecked. After a chmod -R 555, the read only box is checked and Cygwin 
thinks it is a symlink again.
