can't compile jdk on machine with limited ram

[Joe]

I didn't think of ulimit but this is what everything is set at:

cpu time               (seconds, -t)  unlimited
file size           (512-blocks, -f)  unlimited
data seg size           (kbytes, -d)  524288
stack size              (kbytes, -s)  65536
core file size      (512-blocks, -c)  unlimited
max memory size         (kbytes, -m)  unlimited
locked memory           (kbytes, -l)  unlimited
max user processes              (-u)  478
open files                      (-n)  957
virtual mem size        (kbytes, -v)  unlimited
sbsize                   (bytes, -b)  unlimited

The data seg size seems low but I can't increase it.  Everything else
should be fine.
