[ros-diffs] [cfinck] 39138: - Prepend %_ROSBE_ROSSOURCEDIR% to the files and folders when cleaning. This makes sure cleaning also works properly when you're not in the source dir. It also prevents your tree from being totally wiped if you're i.e. on S:\ and your source tree is in S:\reactos. - Set ROS_ARCH already some places before, so we can skip some 'if "%ROS_ARCH%" == ""' checks Thanks to Caemyr for testing.
