"This is what the standard says" - and we checked everything that we
currently support (back to FreeBSD 7.4, old Solaris, AIX) and all
systems have a poll.h, which is either a symlink to sys/poll.h or
just does "#include <sys/poll.h>".  So it's fairly much a no-op today,
but might prevent compile-time issues on more standards-enforcing 
future systems... (very theoretical, this)

Your patch has been applied to the master branch.
