	Thanks!

	No problem.  I have attached the one line addition below.

	Years ago, I submitted a patch to allow configuration of
the kernel with "./configure", which would configure every driver as
a module, aside from compiling in the initial ramdisk and the initial
ramdisk's filesystem.  I haven't configured a kernel for years; the
boot scripts and hot plugging software do that.  The same binary
build of the kernel can run on all of my x86 hardware.

	That is why I know that 92 files failed to compile on x86 in
2.5.1-pre7, and largely why I care about fixing xd.c.

	Anyhow, thanks for asking.  By the way, if you have any interest
in integrating my "./configure" functionality now, I would be happy to
clean it up and resubmit it.  (It is mostly a patch to scripts/Configure.)
