This is the problem.  Try editing Init.sh down where there a line that
looks like:

  echo "export PATH=$PATH" >> $bashrc

to

  echo "export PATH=\"$PATH\"" >> $bashrc

There may be a few other places where some quoting needs to be done
so spaces are handled.  Maybe some other CygWin users want to look
at this -- Note underscores or hyphens make good separators for file
and directory names!

There is no "export $PATH" that I can see...

GRASS is fooling with the shell it's invoking, but it is not modifying your
~/.bashrc.  Do a "ls -a" in one of your mapsets, and you'll see the file
it has written.  You can add some niceties by putting things in 
~/.grass.bashrc.  I like color listings for instance...
