glibc/misc/efgcvt.c
Roland McGrath 52e9a9d118 Thu Mar 14 06:01:07 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu>
* string/strnlen.c: New file.
	* string/Makefile (routines): Add strnlen.
	* string/string.h [__USE_GNU] (strnlen): Declare new function.
	[__OPTIMIZE__]: Define extern inline implementation of it.

	* stdlib/erand48_r.c: Use __mpn_construct_double instead of ldexp and
	addition, to avoid using anything from -lm.

Mon Mar  4 21:57:14 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/m68k/Makefile: New file.

	* sysdeps/unix/sysv/linux/m68k/sysdep.h (SYS_ify): Redefine.
	(CALL_MCOUNT): New macro, empty unless [PROF].
	(ENTRY): Do CALL_MCOUNT just after the label.
	(JUMPTARGET): New macro.
	(SYSCALL_ERROR_HANDLER): Fix syntax.

Thu Mar 14 04:20:48 1996  Roland McGrath  <roland@charlie-brown.gnu.ai.mit.edu>

	* sysdeps/unix/sysv/linux/init-first.c (init): Call `__personality'
	function instead of using inline asm i386 syscall.
	* sysdeps/unix/sysv/linux/syscalls.list: Add personality syscall.

	* posix/unistd.h [__USE_BSD]: Declare usleep.

	* misc/efgcvt.c (MAXDIG): New macro computed from <floats.h> constants.
	(fcvt, ecvt): Use it for buffer size.

	* stdlib/drand48-iter.c (__drand48_iterate): Use u_int64_t instead of
	conditionalizing long vs long long.

	* stdlib/drand48-iter.c (__drand48_iterate): Don't check for null
	pointers; never return EFAULT.
	* stdlib/drand48_r.c (drand48_r): Likewise.
	* stdlib/erand48_r.c (erand48_r): Likewise.
