"test" producing unexpected results after "chmod"




With Linux, these commands produce expected results:

   $ cd /tmp
   $ touch alpha.txt
   $ test -r alpha.txt; echo "$?"
   0
   $ chmod -r alpha.txt
   $ test -r alpha.txt; echo "$?"
   1
   $ chmod +r alpha.txt
   $ test -r alpha.txt; echo "$?"
   0

However with Cygwin, unexpected results are produced:

   $ cd /tmp
   $ touch alpha.txt
   $ test -r alpha.txt; echo "$?"
   0
   $ chmod -r alpha.txt
   $ test -r alpha.txt; echo "$?"
   0

It seems Cygwin is not able to produce non-readable files.
