>Environment:
gcc version 3.3 20030506 (prerelease); gcc version 3.4 20030509 (experimental); platform-independent
>Description:
If g++ is called with -V option and the only input files are objects and libraries, then the alternative driver called in chain cannot guess the language any more, forgets to put libstdc++ in the collect2 call, and the linker fails.
>How-To-Repeat:
Take a little C++ (Hello, world!) program, compile and link it separately, specifying the -V option in both commands.
>Fix:
Probably, the installation script could create an extra hardlink 'machine-g++-version'; the driver could then insert its basename into the execvp() first argument instead of fixed '-gcc-'. Or give along a -x option depending on the own basename.
