 |And that problem goes away by specifying "-DOPENSSL_NO_ASYNC" to
 |config????? That issue seems to have absolutely nothing to do with that
 |define. None of the .c or .h files indicated in the error above
 |reference it, nor do they have anything to do with the async functionality.

Yes, that is what i did!  I looked into the AlpineLinux abuild
package system, and how they get it done, and after adding this
define the building succeeded.

 |This problem seems to be environmental. The code in question looks like
 |this:
 |
 |# if defined(__STDC_VERSION__) && __STDC_VERSION__ >= 201112L \
 |     && !defined(__STDC_NO_ATOMICS__)
 |#  include <stdatomic.h>
 |#  define HAVE_C11_ATOMICS
 |# endif
 |
 |stdatomic.h is part of C11. A C11 compliant compiler should provide it
 |unless it also define __STDC_NO_ATOMICS__. Your compiler appears to be
 |claiming to be C11 compliant and has not defined __STC_NO_ATOMICS__ -
 |and yet the header file cannot be found.

Yes, no such on musl i think.  But i do not know.

 |Perhaps some kind of setup issue on your machine?

But then not on my alone.  The testing/openssl1.1/APKBUILD does

        perl ./Configure $_target --prefix=/usr \
                --libdir=lib \
                --openssldir=/etc/ssl \
                shared zlib $_optflags \
                -DOPENSSL_NO_ASYNC \
                $CPPFLAGS $CFLAGS $LDFLAGS -Wa,--noexecstack

It is likely that i copied that -Define from there back in May
too, but it was a prerelease, and i did not fixate the fix, and
then have forgotten about it.
