Right. One of our products was defining it for the longest time, and 
suddenly it started breaking on Linux, so it seems like it's very spotty 
whether or not the OS will define this structure. RHEL3 doesn't seem to 
have it, but FC4 does. So does Solaris 10 (x86, anyway), but not Solaris 
9 (sparc). My copy of Cygwin seems to have it, but only in 
<w32api/ws2tcpip.h>.
