I'm also attempting to compile udprelay under Gauntlet 3 on BSD
and am getting "udprelay.c:72: poll.h: No such file or directory".
Please contact me if you've already got this working or know how to,
Any information/assistance on this would be much appreciated.
Thanks in advance.

Title: udprelay using select() instead of poll()
udprelay using select() instead of poll()
I was hoping to use udprelay on a DECstation running Ultrix 4.3 or 4.4.
However, it uses the poll() system call and Ultrix only supplies select().
I looked at the FAQ and this issue was not addressed.
I'll look into making the changes myself, but thought I could save reinventing
the wheel if someone had already done this and had diffs that they could

greater or lesser extent, assembly-line workers. Worse yet, they may become
managers who never write any code themselves."
