+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>
