src/x509.c: in x509_aia_append_string(), use heap pointer from supplied *head, and initialize WOLFSSL_STACK.type (fixes "Conditional jump or move depends on uninitialised value(s)" from 08c1397);

wolfssl/wolfcrypt/asn.h: use WC_BITFIELD for extAuthInfoListSz and extAuthInfoListOverflow bitfields, for C89 compat (fixes -Wpedantic from 08c1397).
