+ * shlib-versions: Add version number for libnss_hesiod.
+
+ * libio/iolibio.h: Remove definition of _IO_* macros.
+ * libio/fileops.c: Define close, fstat, lseek, read, and write as
+ macros to use __ protected versions. Use those functions instead
+ of _IO_* functions.
+ * libio/iopopen.c: Define _IO_close to close.
+
+ * manual/math.texi: Explain the use of the optimizing inline
+ functions.
+ Describe rand_r function and tell about SysV RNGs in introduction.
+

+ directly and not through math.h.
+
+ * sysdeps/i386/i486/atomicity.h: Change return type of compare_and_swap
+ to char to get better code. Fix typo.

+@cindex Optimization
+
+If an application uses many floating point function it is often the case
+that the costs for the function calls itseld are not neglectable.
+Modern processor implementation often can execute the operation itself
+very fast but the call means a disturbance of the control flow.
+
+For this reason the GNU C Library provides optimizations for many of the
+frequently used math functions. When the GNU CC is used and the user
+activates the optimizer several new inline functions and macros get
+defined. These new functions and macros have the same names as the
+library function and so get used instead of the later. In case of
+inline functions the compiler will decide whether it is reasonable to
+use the inline function and this decision is usually correct.
+
+For the generated code this means that no calls to the library functions
+are necessary. This increases the speed significantly. But the
+drawback is that the code size increases and this increase is not always
+neglectable.
+
+In cases where the inline functions and macros are not wanted the symbol
+@code{__NO_MATH_INLINES} should be defined before any system header is
+included. This will make sure only library functions are used. Of
+course it can be determined for each single file in the project whether
+giving this option is preferred or not.

+This function returns a random number in the range 0 to @code{RAND_MAX}

+state for the RNG. Instead the @code{unsigned int} variable pointed to
+by the argument @var{seed} is the only state. Before the value is

+
+I.e., the state of the RNG can only have as much bits as the type
+@code{unsigned int} has. This is far too few to provide a good RNG.
+This interface is broken by design.
+
+If the program requires reproducible random numbers in multi-threaded
