No suggestions on a fix, but thanks for the pointer! This workaround, placed at the beginning of my .vimrc, lets Vim put package directories in the correct location for now:

if has('win32')
let &runtimepath=substitute(&rtp, '/', '\\', 'g')
endif


Interestingly, going the other way (changing from backslash to forward slash) does not work, even with 'shellslash' set.
