added some debugging.  still trying to resolve windows issues; cygpath didn't help since it can only do one path item at a time, and we are trying to translate variables like INCLUDE and such.  may need to revisit that since INCLUDE resolves to something sensible already in shell?  in any case, cygpath can either process a path (which doesn't actually seem to work) or process one path into a dos form of the path, but not both.
