FreeBSD 7 buildworld error

[Derek Taylor]

I csup'ed to RELENG_7_0 (from RELENG_6_3) yesterday and have been       
having problems building world.  After about 10 minutes of building,    
I get the error: cc1: out of memory allocating 97582896 bytes

I have put the full output at
<http://www.personal.psu.edu/det135/freebsd.buildworld.20080229>.       

Someone suggested that I might have a ulimit problem, but that looks    
ok to me:
$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) 524288
file size               (blocks, -f) unlimited 
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 11095
pipe size            (512 bytes, -p) 1   
stack size              (kbytes, -s) 65536

max user processes              (-u) 5547
virtual memory          (kbytes, -v) unlimited

Any ideas?  I can provide more information at request.
