This seems to be the real problem with freebsd-current.
You cannot deal with this problem:
Systems that define _SC_PAGESIZE or _SC_PAGE_SIZE (HP-UX)
don't support getpagesize() so there is no way to fix this
in runtime except if you introduce an additional
HAVE_GETPAGESIZE
in the autoconfiguration.
But even then the code would be badly readable.
I would prefer if the sysconf code would call getpagesize() in userland.
