Back after about 18 months without simutrans and working on another laptop as before -> setting up environment.
Running Windows 8, MSVC 2013 : compiling and running latest svn (and local patches) is working OK.
Trouble to get debug output working again.
Should be "simutrans -debug 3" but when I enter that in the cmd window, simutrans just starts "normally".
Same with the current nightly binary version I tried.
Must have missed an (obvious?) part of documentation.
Any hint appreciated.
