I agree, but why provide that choice at gcc configure time only?

I don't want to have to install two copies of gcc, one that handles
C++ 98 and another that handles C++ 98 + TR1 to be able to choose
which dialect to use when compiling a program. glibc can handle
many dialects of C in a single library. Why should I need multiple
versions of libstdc++ to be able to switch between C++ dialects?
