Are you wanting to merge this before libffi/libffi#805 is merged?

We are not sure how long it takes for the libffi PR to be merged as nobody out there is assigned to review the code for now.

@tajila, any input on this?

I updated the date to 2023 but still kept the version to pre 3.5 as the latest version of libffi is v3.4.4 as listed at https://github.com/libffi/libffi/releases/tag/v3.4.4

libffi/libffi#805 is currently under the code review. We will sync with the latest update to see whether it can be merged very soon.

We should either address https://github.com/libffi/libffi/pull/805/files#r1377953612 or launch test compiles to see if the compilers we're using tolerate that non-C code.

We can wait for libffi/libffi#805 (still under code review) to sync with the latest update given this is literally not our code in OpenJ9.

I just updated the PR with the latest code changes in libffi/libffi#805. So we are able to verify & merge this as soon as possible and refresh it later if any more updates in libffi/libffi#805 (which is likely to be postponed to the end of this month as the developer working on this PR is away for two weeks).
