* The `clock_*' suite of functions (declared in <time.h>) is now available

directly in the main C library. Previously it was necessary to link with

-lrt to use these functions. This change has the effect that a

single-threaded program that uses a function such as `clock_gettime' (and

is not linked with -lrt) will no longer implicitly load the pthreads

library at runtime and so will not suffer the overheads associated with

multi-thread support in other code such as the C++ runtime library.
