Yes, you are correct.  I should have been more specific: I am using
openssl version 1.0.2d, and here is my configuration script:

$ cat openssl-config.sh
SSLDIR=/opt/openssl
./config \
    no-ec2m                         \
    no-rc5                          \
    no-idea                         \
    threads                         \
    zlib-dynamic                    \
    shared                          \
    --prefix=${SSLDIR}              \
    --openssldir=${SSLDIR}          \
    enable-ec_nistp_64_gcc_128

Hm, I've been looking for an excuse to build the latest gcc, now I have.

But I haven't tried clang yet so here goes...

Thanks, Matt.

Best,
