(Not putting the patch and ChangeLog in-text causes quoting
problems now.  Perhaps I could have spotted the bug while
writing this reply!)

I have reason to believe that this patch causes the following
build error (cutandpasted):

rm -f include/limits.h
cp xlimits.h include/limits.h
chmod a+r include/limits.h
rm -f include/README
cp /home/hp/combined/combined/gcc/../fixincludes/README-fixinc
chmod a+r include/README
echo timestamp > stmp-int-hdrs
make[3]: *** No rule to make target
`/usr/local/mmix-knuth-mmixware-as', needed by `stamp-as'.
make[3]: Leaving directory `/home/hp/combined/mmixware-sim/gcc'
make[2]: *** [all-gcc] Error 2
make[2]: Leaving directory `/home/hp/combined/mmixware-sim'
make[1]: *** [mmixware-sim/built.stamp] Error 2
make[1]: Leaving directory `/home/hp/combined'

I presume this patch was not tested with a one-tree cross build,
without any installed target tools, and with configure earlier

checking what assembler to use... "newly built gas"
checking what linker to use... "newly built ld"
checking what nm to use... "newly built nm"
checking what objdump to use... "newly built objdump"

You should be able to produce the error for any (cross) target
given those circumstances, but why not try
"/x/configure --target=mmix-knuth-mmixware"
