Dear all, There is a limitation for tcsh (setenv: Too many arguments) to set the PATH environmental variable as you can see in the attached file with the steps to reproduce it. It probably looks like tcsh limitation and not Cygwin. The "set path=( ${HOME}/bin $path)" is not complaining and sets the path, but it also interprets the space in the paths as a separator. The only Cygwin related issue is probably the /usr/bin that it is added twice. Any workarounds?
