    Hold on a second here.... The first patches I sent you were done
by modifying the defined(linuxalpha) to (defined(linux) &&
defined(alpha)) (the tools/ccsym method). But I was told that there was a
template for linux/alpha, and I should modify that, and so I used the
-D's. Which way do you all want it???
    For what its worth, I agree, the output from tools/ccsym should be
used and not -D's.
    Ok, attached are a new set of patches. First of all, ignore all
previous patches I have sent on this thread. Now these three work on the
idea that 'alpha' and 'linux' are both defined. The former is defined by
CFLAGS in template/linuxalpha, and latter is defined by the gcc on my UDB
(and all other Linux/Alpha systems). This removes the need to add any
defines to the CFLAGS line. To get rid of the other define (-Dalpha), we
simply need to replace each 'defined(alpha)' with '(defined(alpha) ||
defined(__alpha__))', as gcc automatically defines '__alpha__' like it
does 'linux'. If you want me to do this, just ask.
    Ok, now are these patches ok by everyone? :) Thanks.
