compilation failure on freebsd8.0-p3 (acl-related?)

[Jim Meyering]

Hi Bruno,

I'm about to make coreutils pre-release snapshot and discovered
a new compilation failure on Freebsd 8.0-RELEASE-p3.

Sorry I don't have time to delve into it.
In addition to this, there's been enough going on in gnulib
that I'm going to defer the snapshot until tomorrow.

/usr/include/sys/select.h has these lines:
