Stop using -fforce-addr..

It's only used in release media. Also if it's causing a bug with compiling this is the first documented case that I'm aware of. Can you confirm that removing it actually allows this to compile?

CFLAGS="-fforce-addr" is in hardened/x86/2.6/make.defaults. I thought that makes it the default if no CFLAGS are set? I thought I remember seeing a comment about it being put in defaults because it helped against certain ret2libc attacks. > Can you confirm that removing it actually allows this to compile? Yes.
yep. works alright when removing -fforce-addr from CFLAGS in make.conf. Sorry I didn't realize CFLAGS in make.conf circumvent an ebuild's CFLAGS filtering.
