I can confirm this.  Running the tar command under gdb shows a problem at 
gnu/fchmodat.c:94:

94            if (S_ISLNK (st.st_mode))

Here st is a stat structure for directory/1, so S_ISLNK() should be true.  It is 
indeed true on 64-bit Cygwin but not on 32-bit Cygwin.  Someone needs to look 
more closely and find out why this happened.  I'll try to do it tomorrow if no 
one beats me to it.

Ken
