It breaks on Caldera. The errors are:
------ snip ----- bin/sh: syntax error near unexpected token `(/' /bin/sh: -c: line 1: `if which: no gcc272 in (/bin:/usr/bin:/usr/sbin:/sbin:/home/lstguest/hch/bin) which: no kgcc in (/bin:/usr/bin:/usr/sbin:/sbin:/home/lstguest/hch/bin) cc -D__KERNEL__ -I/home.stand/lstguest/hch/linux/include -fno-strict-aliasing -S -o /dev/null -xc /dev/null >/dev/null 2>&1; then echo "-fno-strict-aliasing"; fi' (/bin:/usr/bin:/usr/sbin:/sbin:/home/lstguest/hch/bin) cc -D__KERNEL__ -I/home.stand/lstguest/hch/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -D__SMP__ -pipe -fno-strength-reduce -m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2 -DCPU=686 -v 2>&1 ------ snip -----

If you are using a distribution that ships with a default C compiler that is not able to compile linux kernel, use make CC=kgcc (redhat) or CC=gcc272 (debian) instead.
