/*
 * <poll.h> for the MontaukOS git port.
 *
 * git polls only descriptors it created itself with pipe() -- the stdout and
 * stderr of a spawned sub-process (run-command.c's pump loop, sideband
 * demultiplexing). MontaukOS has neither pipe() nor fork(), so those code
 * paths are unreachable at runtime; this header exists so they compile, and
 * the implementation reports every descriptor ready so that a caller which
 * somehow gets here makes progress into the read() that reports the real
 * error, instead of spinning in the poll loop forever.
 *
 * git's own compat/poll (NO_POLL=1) is not used: it is written against
 * select() and <sys/select.h>, neither of which exists here.
 *
 * Implementation in montauk-compat.c.
