Attached is a patch that takes care of the PATHSEP issue. I made a more
extensive change then what was suggested. I found the file path.c that contained a lot of "Unix/Windows" agnostic functions so I added a function there instead and removed the PATHSEP declaration in exec.c altogether. All to keep things from scattering all over the code. I also took the liberty of changing the name of the functions "first_path_sep" and "last_path_sep". Where I come from (and I'm apparently not alone given the former macro name PATHSEP), they should be called "first_dir_sep" and "last_dir_sep". The new function I introduced, that actually finds path separators, is now the "first_path_sep". The patch contains changes on all affected places of course. I also changed the documentation on dynamic_library_path to reflect the chagnes. Thomas Hallgren
