It's much more complicated :-(
In all versions, spaces and quotes are invalid when defining variables.
One problem is that command-line arguments are parsed by the shell
whereas .wmlrc and shebang-line are parsed by Perl by something like
    split(' ', $string);
Then your example is split into 
    -DFOO="moo
    \"bar\""

I have no solution, sorry.
