[Bug libstdc++/15074] New: g++ -lsupc++ still links against libstdc++

[phython at gcc dot gnu dot org]

The FAQ says that using g++ and -lsupc++ together will link against libsupc++
instead of libstdc++.  This doesn't work on GNU/Linux:
                                                                                
jim@squirrel:~/test $ g++ -o sizeof sizeof.cc -lsupc++
jim@squirrel:~/test $ ldd sizeof
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x7002c000)
        libm.so.6 => /lib/libm.so.6 (0x700f0000)
        libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1 (0x70184000)
        libc.so.6 => /lib/libc.so.6 (0x701a0000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x70000000)
jim@squirrel:~/test $ gcc -o sizeof sizeof.cc -lsupc++
jim@squirrel:~/test $ ldd sizeof
        libc.so.6 => /lib/libc.so.6 (0x7002c000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x70000000)

[Bug libstdc++/15074] g++ -lsupc++ still links against libstdc++

If the only functions from libstdc++.a which you need are language  support functions (those listed in  
clause 18 of the standard,  e.g., new and delete), then try linking  against libsupc++.a (usually 
specifying  -lsupc++ when calling g++ for the final link step will  do it). This library contains only 
those support routines, one per  object file. But if you are using anything from the rest of the  library, 
such as IOStreams or vectors, then you'll still need  pieces from libstdc++.a.

It does say to use g++ though :(  This should change.

Indeed, what FAQ? 

You need to be using gcc, not g++ to do this kind of thing. ie:

gcc -o sizeof sizeof.cc -lsupc++
