Mike,
You should be very careful of quoting here.  Since you use eval, you
could insert extra quotes as part of the command - they won't hurt, and
will make it safer.  Another note is that the user's installation may not
be in C:\cygwin.  The following modification should fix both (and the
extraneous '\', to boot):

     -I/*)
         path="`expr "$option" : '-I/\(.*\)'`"
         cmd="$cmd \"-I`cygpath -m /`/$path\""
     ;;

In fact, you could do even better, by passing the path to cygpath as well:

     -I/*)
         path="`expr "$option" : '-I/\(.*\)'`"
         cmd="$cmd \"-I`cygpath -m /$path`\""
     ;;

I leave the the rest of the cases as an exercise for the reader.  :-D
Oh, and the last line should be 'eval "$cmd"' (note the double quotes).
