Perl includes sys/mode.h which is probably not necessary (it look likes
that it is something for AIX), but it seems that sys/*.h headers
modifications break more than only PostgreSQL. And kernel guys should
fix it. Which means no change for PostgreSQL. Only who will use
opensolaris devel builds 116 could have a problem. I will skip these
build(s) on my buildfarm animals.
