Hello Daniel,

I've been playing with your patch on Mac (OS 11.6 Big Sur) and have
run into a couple of issues so far.

1. I get 7 warnings while running make (truncated):
cryptohash_nss.c:101:21: warning: implicit conversion from enumeration
type 'SECOidTag' to different enumeration type 'HASH_HashType'
[-Wenum-conversion]
                        ctx->hash_type = SEC_OID_SHA1;
                                       ~ ^~~~~~~~~~~~
...
cryptohash_nss.c:134:34: warning: implicit conversion from enumeration
type 'HASH_HashType' to different enumeration type 'SECOidTag'
[-Wenum-conversion]
        hash = SECOID_FindOIDByTag(ctx->hash_type);
               ~~~~~~~~~~~~~~~~~~~ ~~~~~^~~~~~~~~
7 warnings generated.

2. libpq-refs-stamp fails -- it appears an exit is being injected into
libpq on Mac

Notes about my environment:
I've installed nss via homebrew (at version 3.70) and linked it.

Cheers,
Rachel
