Calling the sequence:
setsockopt(fd, XXXX, IP_TOS, &foo, sizeof(foo));
can be tricky. Linux uses SOL_IP for XXXX, whereas Solaris and BSD use
IPPROTO_IP for this instead.
Not sure what MacOS or HP-UX do.
Do the newer versions of autoconf have canned code for detecting what to
use? And if not, can someone please add it?
I just grepped the 2.65 tarball but didn't find anything in there.
Thanks,
