Thanks for the confirmation. poll() on MacOS X 10.4 really seems broken, see
http://lists.apple.com/archives/darwin-dev/2005/May/msg00220.html
http://comments.gmane.org/gmane.os.apple.fink.gnome/1193

I could just disable clisp's use of poll() on Darwin altogether, but it's
better to have an autoconf test. Can some kind soul please run the
following test program on MacOS X 10.4.0:

  $ gcc polltest.c -o polltest
  $ ./polltest

============================= polltest.c =============================
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <poll.h>

int main () {
  struct pollfd ufd;
  int result;
  {
    ufd.fd = 0;
    ufd.events = POLLIN;
    ufd.revents = 0;
    errno = 0;
    result = poll(&ufd,1,0);
    printf("fd = %d: %d/%d %d -> %d\n", ufd.fd, result, errno, ufd.events, ufd.revents);
  }
  {
    ufd.fd = 1;
    ufd.events = POLLOUT;
    ufd.revents = 0;
    errno = 0;
    result = poll(&ufd,1,0);
    printf("fd = %d: %d/%d %d -> %d\n", ufd.fd, result, errno, ufd.events, ufd.revents);
  }

    ufd.fd = open("/dev/tty", O_RDONLY);
    ufd.events = POLLIN;
    ufd.revents = 0;
    errno = 0;
    result = poll(&ufd,1,0);
    printf("fd = %d: %d/%d %d -> %d\n", ufd.fd, result, errno, ufd.events, ufd.revents);
