Would you be willing to wait and see if there are complaints?

No, you don't.  libstdc++ is always searched for in $prefix/lib .
No extra switch is needed.  If this is the reason you believe a switch
to /usr/local as the default would be trouble, you can rest assured.

gcc is designed to just work, regardless of the --prefix setting,
as long as libg++ is configured with the same --prefix.
