[Pgpool-committers] pgpool - pgpool-II: Add including <sys/time.h>.

[User T-ishii]

Log Message:
-----------
Add including <sys/time.h>. Some platforms (AIX) seem to require
this. Do not backpatch since after proposing the patch there was
no feed back from the user who are complaining that and I don't want
to risk touch existing stable releases.
