* 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.
