This had previously worked fine with the version of `cp.exe' included with `fileutils 4.1-1' Workaround: Modify all existing Makefiles by adding the proper file extension to the binary. Example: BIN= foo Should be changed to: BIN= foo.exe -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
