There was a bug in 0.52 with effects similar to this, hopefully though you 
are using 0.53something?

I no longer have acess to any SGI machines to test this myself.

I suppose you could write your own implementation like such: (ptr refers 
to the in_addr structure in lookup_host())

/* top of func */
char *tmpbuf;

...

/* replacing call to inet_ntoa */
tmpbuf = (char *) ptr->s_addr;
sprintf(ip, "%d.%d.%d.%d", tmpbuf[3], tmpbuf[2], tmpbuf[1], tmpbuf[0]);

This assumes host order is little endian, mips is big endian no? reverse 
the order of the bytes for that anyway. And finally, this is all off the 
top of my head, so it may not even compile ;-)

I see from a quick google search that using gcc to compile stuff on irix 
will produce problems with the inet_xxxx() functions due to the way 
gcc and irix cc pass small structures.  If this is the case, I would not 
be opposed to patching around it specifically. inn appears to have a 
replacement implementation (sendmail among other seems to use it on irix).
