* sysdeps/generic/libc-start.c (__libc_start_main): Do

	DL_SYSDEP_OSCHECK here.
	* sysdeps/unix/sysv/linux/init-first.c (init): Not here.
	* sysdeps/unix/sysv/linux/dl-osinfo.h: Include <fcntl.h>.

	* sysdeps/generic/libc-tls.c (__libc_setup_tls): Bail if
	argument TCBSIZE <= TLS_INIT_TCB_SIZE, not just if it's zero.

	* sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Check l_tls_offset
	instead of l_type to decide whether to use TLS_DTV_UNALLOCATED.

	* include/link.h: Comment typo fix.

2002-12-01  Roland McGrath  <roland@frob.com>

	* sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_FSYNC): Set to 200112L.
	(_POSIX_SPAWN, _POSIX_MAPPED_FILES, _POSIX_MEMLOCK_RANGE,
	_POSIX_MEMORY_PROTECTION): Likewise.
	(_POSIX_POLL, _POSIX_SELECT): Removed.
