+@subsection Why doesn't Cygwin tcl/tk understand Cygwin paths?
+
+The versions of Tcl/Tk distributed with Cygwin (e.g. cygtclsh80.exe) are
+not actually "Cygwin versions" of those tools. They are built with the
+@samp{-mno-cygwin} option to @code{gcc}, which means they do not
+understand Cygwin mounts or symbolic links.

+See the entry "How do I convert between Windows and UNIX paths?"
