bad link in documentation

[Piotr GOLONKA]

In libstdc++ documentation , chapter 20, i.e:
http://gcc.gnu.org/onlinedocs/libstdc++/20_util/howto.html

in subchapter about functors, the link to SGI's page is improper:
it should be 
http://www.sgi.com/tech/stl/functors.html
and not
http://www.sgi.com/tech/STL/functors.html

cheers,
