@section Is Fast Code or Small Code preferred?
@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.

A completely broken interface was designed by the POSIX.1 committee to

@comment stdlib.h
@comment POSIX.1
@deftypefun int rand_r (unsigned int *@var{seed})
This function returns a random number in the range 0 to @code{RAND_MAX}
just as @code{rand} does. But this function does not keep an internal
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
returned the state will be updated so that the next call will return a
new number.
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
programs the reentrant SVID functions are probably a better choice. But
these functions are GNU extensions and therefore @code{rand_r}, as being
standardized in POSIX.1, should always be kept as a default method.
