Well you can try something like this:

function win32path
{
    declare file=$1
    file=$( echo $file | sed -e 's,//\(.\),\1:,' \
		`mount | sed -n 's,\([^ ]*\) *\(/[^ ]*\).*,-e s~^\2~\1~,p'` \
		-e 's,/,\\,g' \
		-e 's,:\([^\\]\),:\\\1,g')
    echo $file
}

It doesn't like getting spaces in path names since it only acts upon $1,
but other than that it doesn't do too badly.  I'd be interested in any
improvements though, I'm sure that it's probably simpler to do in perl, but
I don't know it well enough.

I've never found a need for the posixpath version so I don't have a canned
one handy.
