[gentoo-hardened] Problems compiling xen - please help...

[Ed W]

I am trying to get Xen running under a hardened kernel.  The machine is 
currently booted with "selinux=1 enforcing=0".  I am having trouble 
compiling:


gcc -DDEBUG -D_ACPI_ -DTEXTADDR=0x000D0000 -I. -I../../../tools/libxc 
-Wall -fno-builtin -O2 -msoft-float -m32 -march=i686 -D__ASSEMBLY__ 
-DDEBUG -D_ACPI_ -DTEXTADDR=0x000D0000 -c trap.S

...etc...


I have tried various combinations of compiler using gcc-config.  Neither 
gcc-3.4.4 or gcc-3.3.6 seem to do any better, hardened or not

I suspect that this could be a problem with the compiler still using 
some hardend profile despite me asking for a non-hardened gcc?  Can 
anyone please help debug this
