Subject: [gentoo-hardened] NOTICE: GCC 4.3.4 going stable on Hardened

Hello Hardened users, this is just a quick heads up.  GCC 4.3.4 will be going 
stable on hardened profiles shortly.  Unlike Hardened GCC 3.4.6, this version 
lacks default SSP building.  However, FORTIFY_SOURCE=2 
and -fno-strict-overflow are now enabled by default.  Other Hardened compiler 
features (ex. default relro, bind now & pic/pie building) remain enabled - no 
change from 3.4.6.

It is regretable this must be done before GCC4 is SSP-by-default enabled.  
However, more and more packages require the newer GCC.  The stable GCC on 
Hardened has been GCC 3.4.6 for a long time, but this has become an untenable 
situation.  GCC4 SSP-by-default works and will be added in a later revision - 
some GCC4+SSP bugs in grub and glibc also remain to be fixed.

Please follow '2. General Upgrade Instructions' in the 'Gentoo GCC Upgrade 
Guide' [1] when upgrading from GCC 3.4.x to GCC 4.3.x.  The upgrade should be 
relatively smooth, but if you run into upgrade troubles seek help via this 
mailing list, bugs.gentoo.org, or irc.freenode.net, #gentoo-hardened.
