Fair enough, if the Cygwin TCL build doesn't understand Cygwin 1.7 symlinks (as suggested by the TCL FAQ 4.45). - But TCL 'file normalize' is successfully resolving the symlink! - Doublebut TCL 'file normalize' is not meant to resolve a symlink at the end of a path. The normalized path should be 'C:/Cygwin/tmp/x2/foo'. What's going on?
