[GrayJack]

Not much to add, just that it will make easier to make old homebrew/cfw to compile on modern SDK

The change itself seems fine. This isn't a blocking question, but I'm wondering what the purpose of the second commit is. The feat commit 6482a98 seems to implement the change itself, the second 214358d chore: Clean up just changes 18 whitespaces.

It might be better for hygiene overall to just add the first commit and drop the second.

Clean up the header file, we have a bunch of files with inconsistent line endings. Since I got no answers when I brought up the subject of automated formating C code; and had no time to bring the subject again, what I'm doing is at least making line ends consistent every file I have to touch (adding this as a second commit).

It might be better for hygiene overall to just add the first commit and drop the second.

It is kinda ok on rebase-based and commit-based merge, as the commit history are kept intact. But I agree it is not hygenic on squash-based merges.

That's fair enough. I think if we rebase the hygiene concern is answered. Thanks for following up.
