A cheesy, but binary compatible, fix might be:
typedef struct hmac_ctx_st {
const EVP_MD *md;
EVP_MD_CTX md_ctx;
EVP_MD_CTX i_ctx;
EVP_MD_CTX o_ctx;
unsigned int key_init:1; /* Ewww, cheesy use of bitfields... */
unsigned int key_length:31; /* but the sizeof (HMAC_CTX) doesn't change! */
unsigned char key[HMAC_MAX_MD_CBLOCK];
} HMAC_CTX;
