You can always query the "configure" script directly:
<bkoz@haight> /mnt/hd/bliss/src.gcc/libstdc++-v3
%./configure --help
You can do the same thing with gcc

I suggest looking at the gcc and toplevel ChangeLogs for more info...

--enable-libstdcxx-v3 turns on -fhonor-std, so that it is activated by
default (and thus specifying it for the libstdc++-v3 Makefiles is
redundant.)
That's it, for now.
