+When configuring a s390->s390 or cris->cris crosscompiler
+(ok, I haven't hit this yet, but one of these days I'll get me an account
+on an s390, and then I'll need this patch :-), you'll get the
+following error:
+
++ /build/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2/gcc-3.3/configure
+--target=s390-unknown-linux-gnu --host=s390-host_unknown-linux-gnu
+--prefix=/result/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2
+--enable-languages=c
+--with-local-prefix=/result/s390-unknown-linux-gnu/gcc-3.3-glibc-2.3.2/s390-
+unknown-linux-gnu --enable-threads=no --without-headers --with-newlib
+--disable-shared
+...
+*** --with-headers is only supported when cross compiling
+
+This error pops up only when you're using Daniel Jacobowitz's technique
+of slightly changing the target and host tuples to make them different
+enough to force gcc's build system to not try to pull in system libraries
+or headers.  This technique is needed e.g. to build an x86 -> x86
+cross-compiler.
+(The LFS developers ran into the same bug that prompted me to use
+this technique; they point people who run into it to
+http://linuxfromscratch.org/~greg/pure_lfs.txt, which is a different
+way of avoiding this problem.  I think the tuple tweak is the way to go, though.)
+
+config-patches@gnu.org rejected this patch, on the grounds that there
+is only one vendor of each of those two architectures, so the 
+canonicalization is by definition correct.  When I pointed out the
+difficulty this causes for people building s390 -> s390 or
+cris -> cris compilers that are incompatible with the system
+libraries and thus must be built like cross-compilers, he grumped and said 
+"autoconf should let you specify a cross-compiler in some other way than
+comparing tuple strings".
