"Dereferencing Pointer To Incomplete Type" on ARM

[vindicator]

Looks like it isn't just nginx (or even more likely IS an openssl issue)
because I just encountered it again with pjproject:
*****
../src/pj/ssl_sock_ossl.c:1001:5: warning: implicit declaration of function
‘M_ASN1_STRING_length’ [-Wimplicit-function-declaration]
     len = M_ASN1_STRING_length(X509_get_serialNumber(x));
     ^
../src/pj/ssl_sock_ossl.c: In function ‘pj_ssl_sock_get_info’:
../src/pj/ssl_sock_ossl.c:2285:24: error: dereferencing pointer to
incomplete type
  info->cipher = (cipher->id & 0x00FFFFFF);
                        ^
