/usr/share isn't mounted separately, at least in any Cygwin installation
I've ever had.  It's just a directory within /usr, which is within the
mount /.  

Moreover /usr/share should always exist, since many base packages store
files in it.  Does it not exist in your installation?  Do you have e.g.
/usr/share/doc?
