-V and -b fails of g++

[Dana, Eric]

When using gcc 3.4.2 with the -V or -b switch, the appropriate gcc compiler
is invoked. However when using g++ with -V or -b switch, the appropriate gcc
compiler is invoked (well not appropriate any more), instead of the
appropriate g++ compiler. We're in the process of testing multiple versions
of GCC and a possibly a cross-compiler environment. In the old days (2.95.x)
and early 3.x, using g++ with -V and -B worked. Was the change in
functionality intentional, if not, should I file a PR? Thanks.
