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 thatcontained a lot of "Unix/Windows" agnostic functions so I added a functionthere instead and removed the PATHSEP declaration in exec.c altogether. Allto 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 apparentlynot alone given the former macro name PATHSEP), they should be called"first_dir_sep" and "last_dir_sep". The new function I introduced, thatactually finds path separators, is now the "first_path_sep". The patchcontains changes on all affected places of course.I also changed the documentation on dynamic_library_path to reflect thechagnes.Thomas Hallgren
