Yes, but Solaris 8 and glibc disagree about whether _XOPEN_SOURCE_EXTENDED is required. As for FreeBSD, I think your general complaint about it being too picky is invalid; everyone else does things the same way, and standards even require that no extra symbols are defined by standard headers unless otherwise requested. But you seem to have discovered that not all of the appropriate functions are declared when _XOPEN_SOURCE is defined. In addition to getpagesize(), brk() and chroot() should be declared when _XOPEN_SOURCE is defined, for example. For the most part, these are interfaces that originally appeared in BSD and later made it into SUS, and the FreeBSD headers were never updated properly. If you have the time, you could come up with a patch to move the appropriate functions from an '#if __BSD_VISIBLE' to an '#if __BSD_VISIBLE || __XSI_VISIBLE'.
