libstdc++-v3 on RedHat 7 - how ?

[Dr. David Gilbert]

Hi,
  I've just found out to my cost that the libstdc++-2.96-54 which is
present in RedHat 7 is NOT v3 (even though it claims to be).

  Changing the flag in the RPM spec file to tell it to build a v3 version
of the RPMs fails during one of the patches.

Suggestions as to a good way of getting a V3 library going under RH7 would
be appreciated; under RH6.2 I just built libstdc++ separatly; but that was
before the days of the library merge into gcc.

Dave
