Please review and follow the Cygwin problem reporting guidelines at
<http://cygwin.com/problems.html>, particularly the bit about attaching
(as an uncompressed text *attachment*) the output of "cygcheck -svr" on
your system.  In the absense of these details, here's a guess:

Did you install Cygwin on a remote share?  If so, see
<http://cygwin.com/faq/faq_3.html#SEC66>.  BTW, it's the only entry about
"symlinks" in the FAQ.
