%description
This package implements the System V poll(2) system call for Unix-like systems
that do not support poll. For instance, the following Unix-like operating
systems do not support poll:

    NetBSD, prior to version 1.3
    FreeBSD, prior to version 3.0
    OpenBSD, prior to version 2.0
    BSD/OS. (See the BSD/OS man pages.)
    Apple's Mac OS X (prior to OS X 10.3)
    QNX version 6
    4.4 BSD Lite 2 (not generally used by production systems)
    386BSD (pretty much obsolete these days)
    OS/2 (and derivatives)

poll provides a method for multiplexing input and output on multiple open file
descriptors; in traditional BSD systems, that capability is provided by
select(2). While the semantics of select differ from those of poll, poll can
be readily emulated in terms of select, which is exactly what this small piece
of software does.

# Add extra POLL constants used by some sources.
# @todo We can't use patch directly because of EOLs (forced --binary on OS/2).
