So you wan one megapatch for PATH_MAX/MAXPATH issues? Isn't it better to
create smaller patches that can easily be reverted if something goes

Another issue is if code should be #ifdef-ed or unconditional, e.g.
#ifdef MAX_PATH or
#ifndef MAX_PATH
or completely removing the PATH_MAX (MAXPATH) dependency. What about the
Win32 port? I haven't looked into that.
