 I think the fix is "Don't include vm_map.h in a file using a local
 variable named min_offset".  There are are thousands of other instances
 of undocumented namespace pollution in FreeBSD headers.  min_offset
 is one of the least important since it is in a "kernel-only" header.
 (vm_map.h is not quite kernel-only, but probably should be.  It is
 needed only in programs like top and fstat that know too much about
 kernel internals.)
