[gentoo-hardened] compile errors during kernel builds

[Rumen Yotov]

Hi all,
A day or two ago had a compile error during kernel build - rsbac-kernel
(gcc-3.3.3-r6). As i have problems with this kernel for some time,
leaved it for later (compilation went OK for rsbac-6.7.0 and
rsbac-6.7.0-r1 later after recompilation stopped booting 6.7.0-r1).
Today also had such problem with hardened-dev-sources-2.6.7-r3 with the
same config as hardened-dev-sources-2.6.7-r2 nothing changed (except i
think GCC).
Suspect it's a problem with the new GCC-3.3.4, before had gcc-3.3.3-r6
(gave such an error for rsbac-kernel - above).
For a long time am using hardened USE flag, before that used -fPIC and
-fstack-protector, so GCC is hardened.
Never had such problems in kernel compilation and don't want to compile
a new -hardened-GCC. All ~x86 system and using genkernel but that's for
a year and no problems.
PS: Also using PaX and grsec2 for quite a long time - minor problems,
including 2.6.5 kernel.
Suggestions.
TIA
Rumen
