* sysdeps/mach/hurd/bits/posix_opt.h: Rewritten with comments and
multiple inclusion protection. (_POSIX_SYNCHRONIZED_IO, _POSIX_FSYNC, _POSIX_MAPPED_FILES, _POSIX_MEMORY_PROTECTION, _POSIX_POLL, _POSIX_SELECT): New macros, define all these to 1. (_POSIX_SYNC_IO): Add #undef, to remind us that pathconf reports it. 1998-08-12 Roland McGrath <roland@baalperazim.frob.com>
