  This last one would probably work if you escaped the inner quotes.
The issue here is not really an issue of parsing. Any string
surrounded with "" will be parsed as a single string. The
problem appears because these strings aren't quoted inside the
action block. Failing to quote clang++ is a bug. I'm not sure
about <linkflags>, as I think I've seen uses of multiple options
in a single <linkflags>, which obviously won't work if the argument
is indiscriminately quoted.
