Aha - I just realized the problem. The Makefile.am fails to link against
the gnulib library that provides rpl_poll, even though the headers are
pulling in the replacement definition.
There _is_ a gnulib issue, though:
The gnulib module poll replaces both the <poll.h> system header and the
poll(2) system call; but when it replaces the system call, it does so
via a define to rpl_poll directly in <config.h> which is an older style,
rather than the modern-day style of replacing things in the gnulib
replacement <poll.h>. Furthermore, modern style favors splitting
replacement headers into separate modules from like-named functions
(that is, we need a new module poll-h if you want a working poll.h
[pollfd, nfds_t, and the various POLL macros] that can be used for
GNULIB_POSIXCHECK conformance and when you don't tickle the portability
limitations of native poll(); and poll [which depends on poll-h] if you
also need the gnulib fixes for the function).
