[gentoo-hardened] Change the configuration of gcc?

[Ernesto Rodriguez Ortiz]

I had problems compiling gnome in my system that uses the profile 
selinux-hardened, the problem was with Glimm whose solutions found in 
http://bugs.gentoo.org/show_bug.cgi?id=217112 # c5 where I was told to do: 
 gcc-config i686-pc-linux-gnu-3.4.6-hardenednossp & & source / etc / profile & 
& emerge -1 glibmm
After this glibmm will compile without any problems, but What are changing the 
configuration of gcc according to which the problem of glibmm can bring other 
problems to compile packages?
