[stunnel-users] stunnel 4.16 /mis-checking getaddrinfo() on FreeBSD

[Tomoyuki Murakami]

  Stunnel 4.16 on my FreeBSD 6.1, configure has mis-checking about
getaddrinfo(),

config.log says,

configure:23030: checking for getaddrinfo
configure:23050: gcc -o conftest -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith   conftest.c -lz -lutil  -pthread -lpthread >&5
conftest.c: In function `main':
conftest.c:74: error: `NULL' undeclared (first use in this function)
conftest.c:74: error: (Each undeclared identifier is reported only once
conftest.c:74: error: for each function it appears in.)
configure:23056: $? = 1
configure: failed program was:

...
| #define HAVE_GETNAMEINFO 1
| /* end confdefs.h.  */
| #include <sys/types.h>
| #include <sys/socket.h>
| #include <netdb.h>
| int
| main ()
| {
| getaddrinfo(NULL, NULL, NULL, NULL);
|   ;
|   return 0;
| }
configure:23079: result: no

Yep, NULL was undefined.
A trivial patch for workaround.
