This change does not make sense to me.  The assert is about the initial
iteration beginning at the "root" level, and at the same time previous
iteration ended at dir_sep.  On mingw you would probably need these two as
separate tests.  In other words, I would understand if the fix were like
this:

	if (it begins with dos_prefix) {
        	/* this is never true outside windows */
		copy the dos prefix out and advance comp_start as
        	necessary;
	}
        while (*comp_start) {
        	assert(is_dir_sep(*comp_start));
                while (*++comp_end && !is_dir_sep(*comp_end))
                	; /* nothing */
		...
	}
