After building GHC, and then doing `git status` I get Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) (commit or discard the untracked or modified content in submodules) modified: libraries/libffi-clib (modified content, untracked content) I have never so much as cd'd into lifff-clib! Doing `git status` in there gives Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) modified: aclocal.m4 modified: fficonfig.h.in I can show the diffs if you like but some are like -/* The size of 'double', as computed by sizeof. */ +/* The size of `double', as computed by sizeof. */ Others are like -# Copyright (C) 2003-2025 Free Software Foundation, Inc. +# Copyright (C) 2003-2018 Free Software Foundation, Inc. Should these files be in the repo at all? Should I open a ticket? Simon
