    It breaks on Caldera.
    The errors are:

    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)

    The problem is that the which output is not ignored.
    The following patch fixes it:

    I personally dislike the 'autmatically detect kgcc and gcc272' patches a lot,
    and I think we should put a sentence like

    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.

    into README, instead of fiddling around with a command/program with lots of
    different and incompatible versions.
