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.
