This error is from the Autoconf code that parses arguments, it currently
disallows characters other than alphanumeric, minus, dot, or underscore
in --enable/--disable/--with/--without arguments.  I suppose this should
be fixed in Autoconf.

However, there is also a bug in configure.ac, and with that fixed, you
will be able to use
  --disable-libstdc__-v3

(i.e., with the plus signs converted to underscore).  Once GCC switches
to a fixed Autoconf version, the plus sign conversion will not be needed
any more.

Patch posted at <http://gcc.gnu.org/ml/gcc-patches/2008-01/msg01029.html>.

Cheers,
Ralf
