if libc.so has nothing to do with STL. Why I can build a application like
this in Linux without "stdc++". 

  g++ -o test test.c 
  
  test.c is using <map> <vector> and it works. 

  ldd test
  libpthread.so.0 => /lib/libpthread.so
  libm.so.6 => /lib/libm.so.6
  libc.so.6 => /lib/libc.so.6
  /lib/ld-linux.so.2 => /lib/ld-linux.so.2
