There was a problem hiding this comment.
ACK 5803f5f - performed the update myself and got the same change: check_20257_subtree.
Tested master & this PR on Ubuntu with GCC 9.3.0. I think it's worth doing this to remove the warning output and save the spurious bug reports.

Update libsecp256k1 subtree The first subtree merge brings us to the same commit as upstream (bitcoin/bitcoin#20257). The second subtree merged brings us to current master, which includes most of our local changes. After this, our remaining local changes are: - 75f9f8f (the change to `secp256k1_scalar_get_b32`) - e917cb6 (compile with C99)
