    2525C++ programs need to link to the standard C++ library (<tt>libstd++.c</tt>) and the C++ front-end ('''g++''') is required to perform the linking task. Do not add '''-lstd++''' to the command line of '''gcc''', '''ld''' or a '''specs''' file.

     27The rationale is quite simple: Linking c++ is more than "just adding a library". G++ reflects this thought and treats libstdc++ as an internal implementation detail users do not need to know about or touch.

     29On some targets/with some compilers "linking c++" is effectively "just adding -lstdc++" but on most others it is more. What confuses some users is "gcc ... -lstdc++" once having been worked with old gcc (IIRC, gcc < 4.0) on i386 targets.
