+  # too ...  and this requires using the host's compiler, which cannot use
+  # the same set of CPPFLAGS as the target. If we specify the sysroot
+  # using CC instead then we don't interfere, because we are only
+  # specifying the *host* C compiler.
+  #
+  # Configure flag notes:
+  #  1. It's vital that this compiler runs in the bootstrap machine, and
+  #     targets the same machine (TARGET_STAGE1) so that the stage 1 GCC
+  #     is used instead of the compiler of the build machine.
+  #  2. See gcc.morph.
+  #  3. Disable searching /usr/local/include for headers
+  #  4. This flag causes the correct --sysroot flag to be passed when
+  #     calling stage 1 GCC.
