How to build libstdc++ ?

Hi

I was trying to build 'libusb', got a problem
and noticed that I don't have 'libstdc++' in
my build directory.
How do I enable libstdc++ to be built ?
I thought it was built by default along with glibc
because I didn't find any package (except in compat)
and didn't find any option in configuration
to explicitly build libstdc++.

Regards,
