options -shared and -static

[ing]

I want to create a shared library which links libstdc++ static. It would
give me a 
possibility to use this shared library on any LINUX-Machine,
independently 
of libstdc+-release on it. 

I link my shared library with options:
gcc ... -shared -static -o MyLib.so ...

It doesn't work! MyLib.so use the .so-version of libstdc++, not the
static-version!
Why?  

Thanks,
