I was refering to -Wno-pointer-sign, no doubt my memory degrades as I 
grow older.

You/I/We have two options:

1. Run make buildkernel as make -DWITH_GCC3 buildkernel, or

2. Patch src/sys/conf/kern.mk using this patch, which will accomplish 
   the same as above:

Is the need of using -DWITH_GCC3 documented somewhere?
It's not listed in src/UPDATING as far as I can tell.

I'm currently compiling both kernel and world on the aforementioned 
6.4-STABLE system and it. Compiling the kernel doesn't stop with error 
messages such as:
