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'  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.
