@tiran Can you verify that the proposed blake2 typo fix is correct?

EDIT: Looking at the file, I see that lines 49-51 being, in main,

#ifdef HAVE_AVX
#ifndef HAVE_SSE4_1
#define HAVE_SSE4_1

makes it likely that line 56 should be #ifndef HAVE_SSE4_1 instead of #ifndef HAVE_SSE41.

@ambv Do build issues like this get backported to 'security' versions?

@nono303 We close bugfix issues after the corresponding PR is backported to previous versions, just to not lose track.

But this fix hasn't merged into branch 3.9 and lower, people who want to build version before 3.10 still got this bug.

This is standard. Non-security bugfixs are essentially never backported by us to versions that only get security-fixes.
