As requested, here's the correct version of
http://gcc.gnu.org/ml/gcc-patches/2003-03/msg01858.html.

The problem here is that these aren't set by every machine (some use the
default values, set later in configure.in). Accordingly, when one is
set
by a BUILD machine, it overrides the defaults for the HOST and TARGET
machines, which is almost certainly wrong.
I've been considering breaking the file up so that it isn't run through
three times; but in the course of doing that I ran into things which are
simple errors, like this. So I'm dealing with those now.
Bootstrapped i686-pc-linux-gnu.
* config.gcc: Clear xm_file, md_file at the beginning of each pass.
