Subject: setup.c: Prepare for Windows directory separators.

This turns two switch/case statements into an if-else-if cascade because
we later do not want to have

        case '/':
    #ifdef __MINGW32__
        case '\\':
    #endif

but use a predicate is_dir_sep(foo) in order to check for the directory
separator.
