	__DYNAMIC_REENT__.
	* libc/include/sys/reent.h[!_REENT_ONLY]: Change _REENT macro to be
	call to __getreent() function if !__SINGLE_THREAD__ and
	__DYNAMIC_REENT__ is set.

	their __libc_ counterparts.
	* libc/sys/linux/io64.c: Add __libc_ prefix to lseek64 and open64
	and weak-alias to regular names.
	* libc/sys/linux/pread64.c: Rename to __libc_pread64 and weak-alias

	name with __ instead of __libc_.
	* libc/sys/linux/siglongjmp.c: Include <machine/weakalias.h>.
	Rename siglongjmp to __libc_siglongjmp and weak-alias to siglongjmp.
	Call __libc_longjmp instead of longjmp, from __libc_siglongjmp.

	it to wait.  Rename wait3 to __libc_wait3 and weak-alias it to wait3.
	* libc/sys/linux/include/setjmp.h: Use __jmp_buf in sigjmp_buf
	type and typedef __jmp_buf to jmp_buf.
	* libc/sys/linux/machine/i386/Makefile.am: Add syscalls.c and
	setjmp.S.
	* libc/sys/linux/machine/i386/Makefile.in: Regenerated.
	* libc/sys/linux/machine/i386/crt0.c: Add support to clear .bss
	section.
	* libc/sys/linux/machine/i386/socketcall.h: Change to use __libc_
	prefix for function macros and then use weak_alias() to regular names.

	to be flockfile() and funlockfile() respectively.
	* libc/sys/linux/sys/types.h
	* libc/reent/getreent.c: New file.
	* libc/sys/linux/flockfile.c: Ditto.
	* libc/sys/linux/funlockfile.c: Ditto.
	* libc/sys/linux/getreent.c: Ditto.
