[PATCH] some systems don't have (and need) sys/select.h

[Robert Schiele <rschiele@gmail.com>]

The select stuff is already in sys/time.h on on some systems like HP-UX
thus we should not include sys/select.h in that case.

This patch replaces my previously sent patch
"HP-UX traditionally has no sys/select.h".
