Yes.  See http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#5_4 for more.

If ye love wealth greater than liberty, the tranquility of servitude greater
than the animating contest for freedom, go home and leave us in peace.  We seek
not your counsel, nor your arms.  Crouch down and lick the hand that feeds you;
and may posterity forget that ye were our countrymen.            - Samuel Adams
