Going in circles trying to compile 1.1.1a with strict C99 and no
optimizations and with a ready to debug and single step resultant
library. Ran headlong into crypto/bio/b_addr.c where we see :
176 /*-
177 * addr_strings - helper function to get host and service names
178 * @ap: the BIO_ADDR that has the input info
179 * @numeric: 0 if actual names should be returned, 1 if the numeric
180 * representation should be returned.
181 * @hostname: a pointer to a pointer to a memory area to store the
182 * host name or numeric representation. Unused if NULL.
183 * @service: a pointer to a pointer to a memory area to store the
184 * service name or numeric representation. Unused if NULL.
185 *
186 * The return value is 0 on failure, with the error code in the
error
187 * stack, and 1 on success.
188 */
189 static int addr_strings(const BIO_ADDR *ap, int numeric,
190 char **hostname, char **service)
191 {
192 if (BIO_sock_init() != 1)
193 return 0;
194
195 if (1) {
196 #ifdef AI_PASSIVE
197 int ret = 0;
198 char host[NI_MAXHOST] = "", serv[NI_MAXSERV] = "";
199 int flags = 0;
200
.
.
.
Where we see NI_MAXHOST and NI_MAXSERV used however those did exist in
RFC2553 and then were removed in RFC3493 and thus strict C99 halts in a
noisey way unless __EXTENSIONS__ is defined.
"crypto/bio/b_addr.c", line 198: error: undefined symbol: NI_MAXHOST
"crypto/bio/b_addr.c", line 198: error: variable length array can not be
initialized: host
"crypto/bio/b_addr.c", line 198: error: undefined symbol: NI_MAXSERV
"crypto/bio/b_addr.c", line 198: error: variable length array can not be
initialized: serv
c99: acomp failed for crypto/bio/b_addr.c
Right.
If I attempt to use "extensions" and other things then this compiles
just fine and the process fails in other places. For now, however, the
values NI_MAXHOST and NI_MAXSERV don't really exist in netdb.h as
far as I can see.
