gcc internal error on buildkernel

After changing my make.conf to list my CPUTYPE as c3 on my

  VIA C3 Nehemiah (999.52-MHz 686-class CPU)

system.  I did a cvsup for /usr/src tag=RELENG_6_2 and successfully  
did a

   make buildworld
   make installworld

I then thought that with my newly compiled tools tuned for the  
processor in my box, I should rebuild my kernel.  I made no changes  
to my kernel configuration file since my previous successful build a  
week and a half ago.  However, now when I recompile the kernel, I get  
an internal compiler error from gcc.  I rebooted the  system and  
tried to build the kernel again, but got the same error.

The last bit of the make output is

 >>> stage 2.3: build tools
cd /usr/obj/usr/src/sys/DOBBY;  MAKESRCPATH=/usr/src/sys/dev/aic7xxx/ 
aicasm  make -DNO_CPU_CFLAGS -f /usr/src/sys/dev/aic7xxx/aicasm/Makefile

A copy of my make.conf is at

Any clues or suggestions would be most welcome.
