Update. 

1998-09-03  Philip Blundell  <pb@nexus.co.uk> 
 
	* sysdeps/arm/bits/endian.h (__FLOAT_WORD_ORDER): Define to big 
	endian. 
	* math/math_private.h: Use __FLOAT_WORD_ORDER rather than 
	BYTE_ORDER. 
	* string/endian.h: If __FLOAT_WORD_ORDER wasn't defined by 
	<bits/endian.h>, make it the same as __BYTE_ORDER. 
 
1998-11-27  Ulrich Drepper  <drepper@cygnus.com>

	* math/math.h: Avoid using long double functions in generic macros
	if __NO_LONG_DOUBLE_MATH.

	* sysdeps/arm/dl-machine.h: Fix handling of weak undefined symbols
	during bootstrapping.
	* scripts/config.sub: Add Netwinder specific matches.
	Patch by Scott Bambrough <scottb@corelcomputer.com>.

1998-11-26  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de> 
 
	* Makeconfig ($(common-objpfx)sysd-dirs): Use automatic variables 
	if possible. 
	($(common-objpfx)sysd-sorted): Likewise. 
 
1998-11-27  Andreas Jaeger  <aj@arthur.rhein-neckar.de> 
 
	* sysdeps/libm-ieee754/e_log.c (__ieee754_log): Add declaration of  
	local variables t1,t2 only if needed. 
 
	* sysdeps/libm-ieee754/e_atan2.c: Added braces to avoid compiler
	warnings.
	* sysdeps/libm-ieee754/s_truncf.c (__truncf): Likewise. 
	* sysdeps/libm-ieee754/s_trunc.c (__trunc): Likewise. 
 
	* sysdeps/mips/mul_1.S (Loop): Add closing comment to avoid 
	warning. 
 
1998-11-27  Andreas Jaeger  <aj@arthur.rhein-neckar.de> 
 
	* math/math.h: Add brace to correct #if expression.
