+# Stage 1 GCC's fixincludes process created a limits.h before there was
+# a real limits.h available for the target. This step (taken from Linux
+# Linux From Scratch) creates a better one so that stage 2 GCC can compile.
+#
+# THIS IS A FRAGILE HACK! We need to replace the headers. The only way to
+# overwrite files in a staging area is to install a new chunk.
+# This is undesired behaviour in the long term, as we want to never
+# have overlaps, so this functionality may go away.
