[exim] IRIX build: daemon.c won't compile

I'm now trying once more to build Exim 4.30 on our IRIX server (since
the SGI "freeware volunteers" never seem to get around to releasing a
new binary ;-/)

Unfortunately, it fails in the following manner:

        gcc -c -O -I.    acl.c
        gcc -c -O -I.    child.c
        gcc -c -O -I.    crypt16.c
        gcc -c -O -I.    daemon.c
daemon.c: In function `handle_smtp_call':
daemon.c:144: `socklen_t' undeclared (first use in this function)
daemon.c:144: (Each undeclared identifier is reported only once
daemon.c:144: for each function it appears in.)
daemon.c:144: parse error before "ifsize"
daemon.c:320: `ifsize' undeclared (first use in this function)
daemon.c: In function `daemon_go':
daemon.c:1391: `socklen_t' undeclared (first use in this function)
daemon.c:1391: parse error before "len"
daemon.c:1528: `len' undeclared (first use in this function)
*** Error code 1 (bu21)
*** Error code 1 (bu21)

Any ideas?


Exact OS version is 6.5 6.5.16f. Exim is 4.30, like I said. Maybe there's now a newer version I could try, but this is the one we're using on Linux...
