name: stage2-gcc-fixed-headers
kind: chunk
install-commands:
# 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.
